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

Thats exactly what Tom at Axiom told me and he seems to know some if the engineers a Yamaha.

Also, if you look closely at the specs for the 559, 661 and 663 you will see that they have different max power outputs at 8 6 and 4 ohms.

The 559 was shown by audioholics to be a very beefy receiver, the 661 not quite so powerful. On paper, the 663 looks closer to the 559, but until someone does some testing we won't know for sure.

Whatever you think of the power side, they sure hit a home run on the features.

Thanks guys,
Man, I would really love to get the Denon, but just dont have the Benjamins right now, in fact I already went way over budget getting the M80's.

I think I will tough it out, and if necessary break out the NAD.
It would be great if I can try it out and still have the option of returning the AVR, but not sure what the typical delivery time for the M80's would be, and need to check the return policy a Tweeters for the AVR.

Silly question, if I do decide to use the NAD as a pre-AMP to the Yamaha AVR, will the volume control still be based on the AVR or the NAD?

Well, for the first thing, the NAD would be used as an amp (assuming it has inputs that go directly to the amp section, bypassing the pre-amp section). The volume control would be on the Yamaha.

Right, sorry that makes sense.

Now another question, and pardon my ignorance:
Would bi-ampliication have any role in this case?

I'm beginning to worry that the NAD wont handle the M80's either...it's rated as only 60W per channel at 8ohm, and 190W IHF dynamic power at 4 ohm...whatever that means

No, biamping wouldn't be involved here. The NAD would be fine.

NoR, another welcome. Enjoy your M80s and 663. It's highly likely that the 663 will provide all the volume that won't cause permanent hearing damage.

NoR - I purchased the 663 several weeks ago. I am now saving up for a set of Axioms. The original (and current) plan is to go with an M60 - 500 system. HOWEVER, reading all the posts in here about the journey to the M80 mecca, I am, of course, second guessing myself. I had posted in a separate thread earlier asking about the 663 and the M80's. Response there was about what you are hearing here. Probably fine - but no one will say with the certainty that they do on the Denon. So, long story short, I think several here, with me on the list will be interested in your review of the M80 performance related to the 663. Definately looking forward to it..........Argon

I see Amazon has a Yamaha RXV1700 on sale for $500 bucks.
Would that be good enough to power the M80s?

Yeah, my gut's telling me the Yammy will do fine.

I'll report once I get the spkrs.

I lamented over the same thing Argon...M60 vs M80.
My room isnt even that big, so initially I thought the M50's or 60's will be fine. But I finally decided on the M80s because I really dont want to miss out on the differences in sonic and sound quality, and it's only an extra $340 (only $170 more per spkr).

The M80 has one more tweeter and one more mid range woofer than the M60, you have to figure it's going yo make a difference.

The best thing to do is really audition each of them for yourself. I just didnt have the patience, I want these bad boys already!
