which leads to guestimation...which I personally dislike but unfortunately a necessary evil in this case.
1. you shouldn't have to guesstimate
"it doesn't actually list the power output in a clear manner "
I think the word obfuscation is appropriate: "the hiding of intended meaning in communication, making communication confusing, wilfully ambiguous, and harder to interpret"
Yamaha isn't the only one doing similar things. I see Marantz has one power spec on their 8077 amp, of 210 w for 1 channel at 1Khz & 10% distortion. Too bad - I was going to use them as an example of a AVR company doing it right
Marantz is also guilty, just not quite as guilty as Yamaha with half dozen different ratings and a whopper of a power spec meant to impress not inform. maybe they are too embarrassed to publish the actual power supply size
let's put it this way...in the AVR world, this kind of practice is "accepted" by some companies in a competitive world. but I still believe the vast majority of dedicated amp mfg's wouldn't be doing this. Yamaha used receiver amp mentality in a separates market & the 2 aren't the same.
for anyone looking at separates, putting your money into good amps is an important choice. otherwise, why even bother? to me, inflating or giving multitude of confusing power ratings just makes that brand less desirable to an informed & serious amp buyer.
IOW, Yamaha (& Marantz) are actually hurting themselves selling excellent, hi-end prepros along with amps with inflated, misleading specs.
if Yamaha wants to sell an 11 ch amp good enough for the separates market, they should have put in the transformer and capacitance to make it worthy, not wimp out on a flagship receiver grade amp all I can say is - I would never buy this amp even if I owned the CX-A5000
too many really good alternatives that will far outperform it and not cost an outrageous amt, as long as you don't want a Krell, Theta, etc
for someone with more $$, you can find used & highly respected Parasound Halo A51's for ~$2500, get 2 and a cheap mid-range 2 ch amp from Emotiva for $300 and not need anything else for a very long time. an A51 has a 2.2 or 2.4KVA transformer, not some receiver sized 850 VA trannie
at that power output, what's the point of this $3K amp? might as well buy the receiver version!
I'm not in the Emo fanclub, but with $3000, I can put a nice down-payment on 2-5 ch XPR-5 amps that will blow the Yamaha away & get their cheap 100 UPA-200 125 wpc for the heights/presence. total cost - $4377
or the 7 ch Outlaw 7900 monster (7 X 350 w @ 8 ohms) + 1 Emo XPA-5. total cost - $4498
and there are other lower cost combinations since the presence & rear channels won't need the power.
or keep that older AVR you aren't going to get much for on Ebay & use it for heights and rears.
the point is - there are many alternatives that will provide far more than your "65 wpc all channels driven" & yet not break the bank.
David, come on, be honest, even at $3000 price point, that's pitiful power for an amp meant for the separates market.
