Hi;
Has anyone used ATI amp with Axiom speakers? I'm planning to purchase a pair of M80ti to replace my ancient speakers and would also like to get an amplifier to be used with my HK 435 (as pre/proc). Thanks a lot.
The ATI 2000 will give you 300 watts per channel for the 4 ohm Axiom M80's, this should be a very nice amp for the speakers. How many channels will you be looking at? I believe a forum member by the name of NeverHappy had an ATI amp but he seems to have been AWOL for the last several months, *poof* ... gone like the wind.
By the way, welcome to the board Image!
I have a friend who had the ATI 2505? amp driving a pair of Michaura M665 towers (very much like the Axiom M60s). He replaced that amp with a Parasound Halo. The ATI, ran cool, quiet, had great sound quality at low or high volumes, and was a terrific amp. Looked like a piece of serious Soviet military hardware. He likes the Parasound, but it runs very warm to the touch. The Parasound is prettier. The ATI is one serious and terrific piece of equipment. I highly recommend their amps.
Welcome!
ATIs have a nice looking design and many options to start small and add channels.
Any model would work with your 435.
Thank you all for your informed responses, I'm planning to get the ATI 2007 (my other alternative is Parasound A51). I'm hesitate as of when Axiom will start offering wood venier but not sure if I can wait that long after reading all wonderful reviews!!!
ATI has been making some serious amps for years. They used to be callled SAE. They have a huge third party business producing amps for other companies that put their own moniker on them. One particular company that is very popular around here, Outlaw, is made by ATI. ATI's own are a step up. I have been considering one to replace my limping along Harmon Kardon PM-665xi.

......And back like bad gas! Took some time off from the forums. Had to make some changes to the sideline business and I re-did most of my system again. It took me way longer then planned.
As for ATI, they will power anything and everything just fine. Great amps that have incredible power reserves.
I forgot to mention that I still have an ATI kicking around here. The AT3007 - 7 channel monster. I'm not using it at the moment but it's around here somewhere!
Hey John I hope you've been doing well. Welcome back.
Hey wid, nice to see ya! Hope all has been well for you and yours!
Never: good to see you posting on this board again. I was wondering what happened to you.
I too say welcome back from your 2 1/2 month hiatus.!
2 1/2 months? Was it really that long? Jeeeez time moves fast. A belated Merry Christmas and Happy New Year to all! lol
Time really flies by when you having fun!
LOL!!!

What do you use in place of the ATI for your 7.1 amplification?
Neverhappy:
Can I have the ATI amp if you are not using it? Please? :-)
I am trying to decide between these two amps:
Earthquake Cinenova Grande (300wpc x5)
Outlaw Audio 7700 (200wpc x7)
I know they are not strictly comparable, but they fall more or less within my budget.
Any advice?
Richie: I am also looking at the new Outlaw amps. I think the 7500 will fill my bill. But, I'm waiting to see a few reviews and I have a few questions for the new owners.

This was easy, Earthquake Cinenova Grande hands down...........it's not even close. That thing is the HEMI of HT amps. Very nice amp.
I should say however that I'm a little bias. I'm not a fan of Outlaw. Had a few of their products.........all for a short time. Just wasn't my thing.
Never: what didn't you like about the Outlaw products?
I was afraid you were going to ask that. I don't want to turn this into a flame war but the last product I had from Outlaw was the 990 and It was just ok. I had it for a few weeks and ditched it. I also tried the 7125 and thought it was very under powered.
But that is me. There are lots of folks around here who run the stuff and love it.
Yes, I think I need the Earthquake Cinenova to drive my four 4-ohm M80ti speakers. 600wpc@4ohms! Yahoo!
never: thanks for the comment, and, I don't want a flame war either.
As you know, I have been in the audio market for a new receiver, pre/pro and/ or seperate amps for over a year. I finally decided to get a receiver as a pre/ pro and get some seperate amps. I expect the receiver tomorrow. So, now to look at amps.
I understand how a linear amp is suppoed to opperate so I thought that I would look at the THD and spectrum parameters. I did and everyones metrics look good. So, now, I am left with the question of how to determine what to select? What is the basis of my selection?
For the lack of anything better, I am looking at why folks DID NOT like an amp.
If anyone has any other selection metrics that they would like to share, I am listening.
Serious or otherwise!
None within human knowledge, Bernard. As both technology and experience(confirmed by blind listening)indicate, flat frequency response from 20-20KHz, and inaudibly low noise and distortion levels result in transparent amplification and all this is available these days at quite low cost. Factors such as long-term durability can be guessed at, but there're no guarantees. Maybe "look at", as you said, is the right terminology; pick the most attractive appearance, since nothing else may be apparent.
If I were in the market for an amp, I would look at the power-> noise ratio.. try to get something with .005 or less THD, are you fimilar with transistor theory? If you are you should have no problem chosing an amp if you can look at the shcematics, I have found some manufactures that have the actual schematics online..personaly I would stay away from the 7 channel amps that are powered from a single power supply, as the only amp that I have see that I would consider would be the earthequake product, sense each channel has its own power supply. Rat, I would say get a 3 channel amp, and a 2 channel amp. Maybe bryston. Or ATI.. depending on your budget.. get a 2-300watt 3 channel, and a 150-200watt 2 channel for your QS8’s..
John: yes, I sometimes wonder if it might come down to what just looks best.
Thanks.
dakkon: you raise some interesting points. Yes, I am familiar with transistor theory. As for theory, a "properly" designed power supply should not allow pertibations from one channel to effect another. That's theory, and we know that is sometimes (most times in "cheap" amp?) not the case. It has been over 20 years since I was involved in power supplies. I sure that I am not current in their specific schematic design. The problem that I have found with modern schematics is that as soon as they show an integrated circuit (IC) you are blown out of the water. Many of the ICs are custom made and the information on them is difficult to obtain.
Thanks for your input. Your key points are definitely something for me think about.
<<Power Output: 200 watts @ 8 ohms, 20 Hz - 20 kHz, <0.05% THD; 300 watts @ 4 ohms, 20 Hz - 20 kHz, <0.05%>>
Outlaw monoblocks are <.05% THD. Some don't like the A/B/G design but it works for me.
It also says this:
<<For output devices there are a total of six: four bipolar transistors rated at 15 amps each, and two robust power Mosfets rated at 40 amps each. Dynamically into 8 ohms the 200 will put out 300 watts! In addition it has at its disposal 20,0000 microfarads of capacitance.>>
But I'm not sure what it means!!!!
bug: what that means is that you don't want to short the output terminals. LOL!!! You'll get a big spark.
The Onkyo came this afternoon. I unboxed it and examined it because the wife said that the UPS man dropped it with a thud. Looks like it was tripple boxed and no obvious damage. It will be Saturday before I get a chance to hook it up and try it out. I don't like to rush when I hook up electronic gear and I have several things to do tonight and tomorrow night.
