Posted By: Dduval 6 Months later...my Emotiva RPA-2 Experience - 06/13/09 05:29 PM
I thought I would post this here since this is where my story started. Caution=long post.

Some of you tried to warn me, but like an idiot I wouldn't listen. The reviews and price point of the RPA-2 was just too tempting.

Anyway, I was really, really impressed when I got my RPA-2 back in Jan. Posted a glowing review and everything. I think it was about a month later the problems started with the amp.

While I had no heat or shutdown issues with the RPA-2 like some others, my amp just completely died. The left channel completely went out, nothing, nada, gone. Now the weird thing is when I went to sleep that Saturday night (after listening most of the day)the amp was fine. It went into standby mode and I went to bed.

The next morning I woke up, walked into the living room and noticed the solid red LED was on. I powered up everything and the left channel on the RPA-2 was gone. After doing some trouble shooting, I had to call Emotiva.

Now I will say one thing. Emo was very professional and provided excellent customer service. They shipped a new one out asap and issued a call tag for the defective one. Fedex showed up 2 days later, swapped the boxes out and I had a new RPA-2.

So...while I was a little (actually alot) freaked out the first amp failing after only a month, I now had a new one. I'm thinking to myself "Darn, I new I shouldn't have went with Emo" but was also thinking what was the chances of 2 new amps failing back to back. I remember when Randy (sirquack) warned me of his emo issues.

Well, 4 weeks later after receiving the 2nd amp...catastrophe! While cranking some Gary Moore, BAM! Left channel GONE! AGAIN! I couldn't freakin believe it. I called Emo and asked for Lonnie. I explained to Lonnie what has happen to me and questioned him again about the "pairing of axiom M80's and emotiva". At this point I wanted a different amp, XPA or something, I just didn't want to go thru this again.

Lonnie was very understanding and calmed me down. He also told me there was probably something wrong with my left speaker for this to happen twice with the left channel. He said I had to have a "short" in the left speaker and one of the drivers just had to be defective. Telling me something to the effect that a driver was shorting out for a "split micro-second" (which was why I couldn't audibly hear any problems) thus blowing the left channel out on the RPA-2. I was like what? you're kidding me? right? Now, it's Axioms fault?

My 6 year old Yamaha plays fine and even when cranked to loud volumes, my yammy never faulted once! He then explained to me that most receivers have built in "limiters" and "protection circuits" and the RPA-2 did not. Thus causing the failure. Again, he mentioned the M80's ohms dropping too low as well. We've all heard that story before. I say bull****! They even told me I should send the left speaker back to Axiom to have them check it for a defect.

I did call Axiom and talked to JC. Now, Emo has me thinking there was actually an issue with my left speaker. I just didn't buy that logic cause I didn't understand why my old yammy drove the M80's and the RPA-2 would not, built in limiter/protection, whatever, I didn't care. I just wanted a 2 channel amp with no problems!

So, Lonnie told me to send the 2nd failed RPA-2 back to him and he would personally checked it out. I sent the amp back and they had it for 3 1/2 weeks. Lonnie and I spoke a couple times while my 2nd amp was being repaired. I told him to make absolutely 100% sure they checked it out and do a thorough burn in testing before they sent it back to me. He also told me to make sure I switched the left/right speakers. This way, he says if that "one" (left one) speaker was shorting out, then it would obviously blow the "right" channel of the amp this time. If the right channel blows this time, then we would know for sure it's a defective speaker driver causing the amp to fail. I agreed, as I definitely wanted to know. He even suggested I try setting the M80's to small and route all LFE to the sub only! Explaining that this setting in my receiver would prevent the low HZ from dropping the speakers ohms "too low" and blowing the amp. Again, in my mind I'm saying Bull****! I want my receiver set the way "I want it". To have to have "special" settings to accommodate any amplifier is ludicrous!

Also, I wanted to mention that sometime during this 2nd amp disaster, Emotiva actually discontinues the RPA-2, which just came out in Jan 2009. I think they only had it for sale the first couple months of this year. Emo states somewhere on their forums that the parts, cost of production, etc. became too expensive and they just couldn't offer the RPA-2 anymore, it didn't "fit" into their Business model and marketing strategy or whatever. I found that extremely ironic.

Back to the story. After 3 weeks I called Emo and asked how much longer to repair it, couple days later they ship it back to me. The amp arrives and I unpack it. At this point I just stop, didn't even hook it up or plug it in. I know at this point I'm just gonna put this thing on Audiogon or ebay & get rid of it. My mind was set on getting a completely different amp.

I go back to work and call Lonnie. This whole thing has just driven me crazy and I wanted Lonnie to explain to me "exactly" what failed in the amp before I sell it. Funny thing, he states he was just about to call me and make me an offer. He told me that he looked at the first amp that failed on me and said that on "both failed amps" the exact same resister fried. He said that "those M80's just go so low in ohms" (cough,bull****,cough), that any of his amps would just keep failing because none of the emo amps have a "limiter" built in. He said he would be glad to refund my money, send me a call tag to have it shipped back to him and we can both be done with this. I freaking jumped at his offer! I wanted my money back now and I could go buy a different amp.

A week later...got my refund in full. Right now, you all might want to take restroom break, grab a bite to eat or a coffee refill. \:\) The story continues...

_______________________________________________________________


So while my second RPA-2 was being repaired I had been relentlessly researching different amps. Knowing I was going to wash my hands of this Emotiva amp one way or another. I was tired of this emo/axiom pairing issue, almost sick to my stomach of it. I was determined to find an amp that would blow my balls right off! \:\) I must have read thousands of forum posts, reviews, audiogon listings, more reviews, more posts, more, more, more...even convincing myself I was going to just get a AVR and be done with it. I researched every freakin AVR and amplifier to no end. My eyes where hurting at this point.

Frustrated and weary, I went back to my very first post here on the Axiom Forums...

http://www.axiomaudio.com/boards/ubbthreads.php?ubb=showflat&Number=241765&fpart=1

As I was reading the thread again, noticing again that both Randy and Sean had oddysey amps and I had already read every odyssey review I could find. I gave Klaus a call. As Sean and Randy had told me to do from the very beginning! God, how I wish I would have listened to you guys. I'm such an idiot!

As at least a couple of you know, Klaus is a class act. After a couple weeks and several conversations with Klaus and figuring my budget, I had Klaus start building me a pair Stratos monoblocks with board, cap, resistor and wiring upgrades, in Khartago cases. And then the long 5 week wait began.

As usual, Klaus found out exactly what my needs were, making it clear that my huge priority was pristine sound quality at levels that will, well...you know...blow my balls off! (been married for 24 years, so I have no need for them anyway \:\) )

So the mono's finally arrived last Friday June 5th. They have been running 24 hours a day since.

Now, I won't go into how great they are. I have already done that with my RPA-2 posting and we can all see what that has done to me. Who knows, maybe these will blow up too. As Klaus put it, amplifiers are electronic and sometimes, electronic equipment just fails.

I will say this about my Odyssey monos. So far...(fingers crossed)...

my balls are gone, they came completely & cleanly off, no pain, no snags, nothing, just gone. I have been searching the house for them the last few days. I miss them dearly now... \:\) I think the dogs got them, they both have strange, sort of "revengeful" smile on their faces.

Hope you all enjoyed my story...and I hope this may or may not be viewed as advice for future amplifier purchasers, not sure, it's just one guys experience.

And special thanks to Randy and Sean for leading me to Klaus, as they both tried to do in the beginning.

Respectfully,

Dduval
Seems more like a quality control problem with the amp than a problem with the speakers. The previous issues that people were experiencing with emotiva amps and the M80's is that some models were shutting down and going into protect mode, not blowing channels.

Sorry to hear about all your problems but atleast you have Odyssey monos now .
I agree Dr House, this hasn't been the first time Axiom M80's were falsely blamed (IMO). I think I would have taken it better if the RPA-2 was just shutting down, instead of a resistor blowing...twice at that.

I can tell you I have purposely driven these odyssey monos to ear deafening levels and so far so issues. I can't take those volumes but just for a few seconds as of course I don't want permanent hearing damage.

But so far, so good.

Dduval
And like you said your yamaha runs fine with the same m80's as well as the Odyssey monos. If there was something wrong with the speaker (such as a short) I would think it would have manifested itself with your other equipment, but they work just fine \:\) .
Posted By: CV Re: 6 Months later...my Emotiva RPA-2 Experience - 06/13/09 06:16 PM
Sorry to hear about your luck with Emotiva, but I'm glad you got your money back and are happily emasculated with your new Odyssey amp. The Emotiva amps have always tempted me, but at this point, I just don't see why I'd ever want to support them.
I do give Emotiva credit for their customer service in this matter in the fact they refunded your money without any problems.
Yes, I didn't want to come off bashing Emo as a company. From a customer service stand point, their staff is among some of the best in the industry. What Lonnie did for me was best for both of us and I certainly have to respect that.

Dduval
Wow, what a trial you had to go through!

Dduval, congrats on getting a new amp that you are happy with. I've bought a lot of stuff from Klaus at Odyssey over the years because he makes good products and stands behind them. As a matter of coincidence, I just recently hooked up my Khartago amp again and am really pleased with it. His amps will just about run anything.

When do we get pictures of your Odysseys?
I know this experience was no fun for you, but it sure makes a good story. Thanks for sharing it with us. \:\)
Those sound awesome. I don't think I can rationalize it (hell, I couldn't rationalize a UPA-2), but if I ever do find myself with an extra $1K or so, I may well give Klaus a call.

And, given my prior history, if you believe that, I've got a bridge to sell you...

Yea Ajax, I look back on it now and laugh. It's funny now, I can't believe all the crap, and waiting, and waiting, going without an amp for around 3 months. Man, I was irritable as hell for awhile!

My wife heard it all too, she's just praying these monos don't break. \:\) I don't know who's she's more frustrated with, Emo for putting me in a bad mood for 3 months or Odyssey for decapitating my nuts. \:\)

I'll get some pics up soon. I have them on the floor right as they are too heavy for a 1/4" glass shelf. I already have a 3/8" glass shelf made, just have to install it, but some braces in and set the monos on it. Pics will come...

As long as they don't denutitate your caps and put them in protected mode you should be good to go. ;\)

I'm glad it worked out in the end. I bet Emotiva discontinued those amps because of problems.
Wow, I think I just re-lived a dream from my past. \:\) I agree about Emo's CS, they did try to get things working for me, and in the end Lonnie did refund my money many months later. Axiom has been around a long time. Yeah they have a few bumps in the road, but have a very good track record.

It was simple for me, most AVR's on the market can drive 80's to very loud levels, but Emo monoblocks kept shutting down, something is wrong and it was not the speakers.

Lonnie has had probably 10+ people in recent years that have had issues driving the 80's, as well as other brands like Rockets, it is always the speaker designs fault. Just look at the graphs Lonnie, or (mad scientest) here on Axiom. The 80's don't fall below 4ohms, and only come close at a small FR.

Anyway, DD, I've very happy for you. Wish I would have know you were looking at Odyssey, as I'm considering selling mine to save up for the Axiom 2-channel digital amps. Not because the Odysseys aren't awesome, they are probably the best amps I'll ever own, but I'm just curious about all the buzz on the Axiom amps. \:\) I could have made you a sweet deal, with 18yrs on the warranty left.

glad your happy though..

That's what I was thinking (of course). They only had the RPA-2 up for sale for 2 or 3 months after a year of pre-release hype. To discontinue an item THAT quickly...never seen a company do that before.

That thought did go thru my head Randy. I had read that you were thinking of selling your monos. I'm so freakin gun-shy and have such bad luck with my audio gear I doubt I would ever buy used.

Heck, lately I've been cautious about buying new. \:\) If these mono's hold up for awhile, I'm sure that feeling will pass.

One question I was going to ask you. I don't think I could ever find your initial review/reaction when you first got your monos from Klaus. Did you ever post a review of them Randy? just curious...

Dduval
Odyssey has a 20 yr "transferrable" warranty for upto 2 buyers. So you would have been covered by the warranty...no big deal, glad you like yours..

Here are some pics of mine..






How hot do those puppies run, Randy? Sure are pretty.
Ken, I know you asked Randy, but I'm gonna answer anyway!

MIne amp runs warm. You can comfortably put your hand on top. I've run it hard watching movies. Used to have it hooked up in my HT and it never got boiling or anything.

I should note that mine is just a Khartago stereo amp and not a Stratos in a Khartago case. May make a difference. The Khartagos vent from the top while the regular Stratos have the vents on the side.
FYI-Mine run only slightly warm at moderate volumes. Even when driven extremely hard I can still place my hand on them, never too hot.

Dduval
In terms of design, they will be warmer in A mode, but when they switch over to AB mode, they should run cooler. Ken, I can say they have to have airflow around them... I can't put mine in my AV cabinet as the top one gets way to hot. However, I have one in the AV cabinet, and the other one in the back closet behind everything out of sight, now they are only just warm to the touch.

I think the A/AB type amp in general will run warmer without good ventilation.
Just wait until you break them in over time, this is one piece of equipment I'd about swear has opened up with time and the soundstage and instruments sound better. I leave mine on all the time to keep them fully charged.
Yea Randy, I leave mine on 24/7 per Klaus. As to the breakin time, it was so funny when I asked Klaus...

"so Klaus, are they gonna blow me away right out of the box?"

Klaus answered "NO! They will sound like sh*T right out of the box"

That floored me, then he went on to explain they get better and better with time. Personally, I thought they sounded great out of the box. I have 140 hours on them. I don't know if it's me or the amps, but today I put in Alan Parsons Project Essentials CD and it was just jaw dropping already. I can't imagine them getting better.

It's strange, they are so different from the RPA-2. The other day I was just doing some casual listening (can't remember what was playing) when I thought I heard someone tapping on the window next to my couch. I actually got up and walked over to it and realized it was the freakin CD that was playing. It was awesome! The sound was everywhere, yet only playing from my M80's. \:\)

Dduval
How much electrical consumption do those bad boys take while in on/standby mode?
Dr. House,

Klaus told me when idling, each amp will consume about as much as a 25 watt light bulb. FYI

Being a fan of external amps myself I think I'm qualified to call this bs. It could be a safety factor leaving those amps on. If you ever have the unfortunate accident of those amps going south (catch on fire) with the family sleeping this could turn bad real quick.

I think this is a very bad practice to get into.
I know Rick, I was unsure about all this myself. I can say there is a whole community of seperate amp people on Audio Circle that think we are all BS. I don't know, the Symphonic Line (what Odyssey is based on) has been around a long time, and both manufacturers explain this in the owners manual. I guess I don't design amps, so can't comment on the validity of the capacitors being drained and other breakin terminology. I can say that the amps do sound a little "thin" at first when they have been unplugged for some time, and do appear to open up, or whatever you want to call it, after being used for some time. BS, maybe, but Klaus has been around a long time and it very well respected in the amp community.
Posted By: Wid Re: 6 Months later...my Emotiva RPA-2 Experience - 06/14/09 01:43 PM

I wouldn't take a chance with leaving them on no matter the reason Randy. If it has a power supply, and we know it does of course, it has a chance of catching fire. No matter how small the risk; risking your lovely family isn't worth leaving those damn amps on.
I know Rick, appreciate the concern. Right now I'm not even using them, they are unplugged. Had to rearrange some things when I got the Bluray player, not enough room in my opening. My fault when designing the room, if I only would have copied Rick2's setup. \:\)

Thanks. That was exactly the information I was looking for.
So we've got two Axiom-group no-no's in one post.

1) The amps need to break-in to sound their best.

2) The amps made your system sound different.

Welcome to the amps-matter club. ;\)

Sorry to hear about your Emotiva experience. I've had it both ways with Emotiva.

On the one hand, my LPA-1 has been flawless for several years now. Handles my M80's with ease. Really great purchase that I've never regretted.

And on the other hand, I returned the LMC-1 prepro for a refund. Way too many bugs and overall, too "quirky" for me.

At least they did the right thing and gave you your money back. Perhaps the there's more to the quick discontinuation of the RPA series than they're letting on to. I still don't buy the low-impediance M80's BS from them. Even their flagship MPS-1/2 had problems driving Randy's M80's. And the MPS-1/2 is supposed to be stable down to 2-ohm loads. My LPA-1 is supposedly "only" stable to 4-ohms, yet it drives my M80's to ear-splitting levels without incident. So

Peter, of course it may be that it's Klaus, and not the new amplifier, that's full of it.

If Klaus is full of it, then I guess your saying Rolf Gemein is as well, which I don't have the background and many years as they do, to call BS. I suppose if I designed amps and had the facts to call BS, then I would, otherwise I look up to people that have been around for 30+ years in the high end community.
The thing with Klaus is that his products pretty much speak for themselves so he can get away with his claims despite their tenuous basis in reality.
True, the 20yr warranty caught my attention, unheard of in other amp brands.
Bryston?

Rotel doesn't need that long of a warranty. The never break \:\)
When I started reading the original post and how the second one died and the OP was looking for another amp i started thinking... Odyssey... scroll down a ways.. Oh. A happy ending after all \:\)

I've had my khartago mono's for about 2 1/2 years now and havent had any problems with them. Been powered up 24/7 since i got them and cranked everyday. I did have to adjust the bias and DC offset on one of them because it was way off somehow. Not something the average person would even notice. I didnt until I measured those specs with a meter. Other than that though they have been great. They dont blow up because my M80's go down too low in the bass.. they can crank at near uncomfortable levels for hours no problem. Although they will get pretty hot if Im doing that... But I do run the bias a little higher than normal IIRC.

I do have the dreaded phono preamp issue with my tempest preamp I bought used but I dont use the phono section anyway so although that was kind of dissapointing It wasnt worth me sending the unit back for a repair or upgrade.

The same could be said for pretty much any electronic device. Tv's microwaves, toasters, subwoofers, computers, battery backups. Its one reason they have fuses. Granted the amps dont have a UL rating like most consumer products the chances of a fire arent any greater than anything else...

Same here, I'm glad you are happy with your mono's! How do you like your tempest? I was seriously looking at the candela...
I was extremely surprised to find out that Bryston's plant is in my small city of Peterborough.

I like the tempest quite a bit... Built solidly, always works... what more could i really want. Like i said, I lucked out and mine has an issue with the phono preamp interacting with my power or something along those lines which causes humm in the phono section but besides that its great.
Thanks Haoleb,

I'm undecided about the solid state tempest or the tube candela. Without hearing them both, its a gamble for sure. Only couple hundred $ difference in price. What to do, what to do...

Take care,

Dduval
Buy both ;\)
That's actually the right thing to do Jay! \:\)


Dduval
I still love my RPA-2 amp driving my M80's, hasn't missed a beat.

I can drive the amp to clipping (red light comes on) but that has not changed since I bought them. And listening at that level while not painfull makes me wonder about my hearing over time.

The best part is the amp runs cool and listing for hours at loud volumes during parties never concerns me anymore.

Anyway I am sad you had such a bad experience. I would have been curious if it would have went to the right channel if you switched the speakers. Anyway glad to hear you are enjoying the M80's with your new amp.

I certainly can understand that, when my RPA-2 was working, I loved it too.

I actually was going to swap speakers when I got the second one back, but was too paranoid to even hook it up, it would have been interesting for sure if the right channel went. That definitely would indicate the speaker was the problem.

But so far, my mono's are working great. Thanks for the kind words, take care.
