Axiom Home Page Forums General Discussion Advice from Axiom Owners Help! Yamaha RX-V633

Complete NooB here,

In hopes of slowly building a nice system, I picked up a Yamaha RX-V633 at Tweeters after doing research (it seemed like the best bang for the buck for an AVR).

After doing research on Speakers, I decided on the M80's, and put an order in for them yesterday (CANT WAIT!).

The dilemma is, I am now reading about the concerns of using Yamaha AVR's with these speakers due to the 4 ohm resistance issue.

My room is hard to describe because it is kind of an open living room into a dining area (in an APT), but my guess is I would not need to be cranking it up because the couch is about 12ft from the Plasma.

So should I return the AVR, and purchase a Denon 3808CI which may put some damage on my credit, not to mention marital issues

Other background info:
I won't have a 5.1 setup (due to wiring difficulties) i.e less power consumption for the AVR?

I also have a spare old NAD integrated AMP lying around:
NAD C340 http://207.228.230.231/info/NAD_C340.pdf
Would it be a good option to hook up the M80's through this if I run in to probs?

sorry bout the marathon post, im hurting inside

Welcome!

I'm thinking the Yamaha may do OK, as it's 95 WPC and many owners here have Yamahas. IIRC, Yamaha is on the good list with Denon, Outlaw, H/K as far as receivers that can power the M80s.

It is nice to have that amp as a back-up, and it couldn't hurt to run them through it, but it may not be necessary.

I expect others with more personal experience to chime in shortly.

Let us know how you like the speakers! We love reviews.

do you mean the 663?

Yes sorry, 663.

I know that mdrew ran M80s with a 661 to excess of 100dbs in a 14x16 room (I think those are the dimensions). How big is your room? Mdrew thought that the 661 was a very good reciever, and worked well with the M80s.

The problem with Yamaha is no one is sure that the same P/S and amp that were in the 661 are now in the 663, which is why Axiom has them on the not so good list.

Before panicking I would try it out and let us know how it works so we can put an end to the debate as a few others have looked at the 663 with M80s. If it turns out to not work the NAD will do fine or as you have suggested return the 663 for the 3808 which we know works great.

With all due respect, Yamaha has been on Axiom's not so good list long before the 661 showed up. As you all know, I love Yamaha and will continue to use their products until they no longer are suitable for my speakers. The 661 and the 663 share the exact same wattage rating. I believe they use the same amp.

Robb, I was just re-iterating what Axiom has stated as being the reason Yamaha is on the not for use list with M80s, because in the past during their testing, from year to year Yamaha would make P/S changes in certain models which would cause problems even though the previous version worked with out any problems.

And Robb if you haven't noticed you don't own M80s so you can continue using Yamaha .

As I said the O/P should try the 663 before panicing, most people are not having problems, but I do recall somone with the 1800 had some sort of problem or was that just the YPAO and the center channel?

Its only a matter of time my friend

For the new house?
