for those that lie and say I haven't.
Yamaha "may" have 35% power output driving all channels when overloaded with a:
continuous loaded sin wave across all channels simultaneously
But where does it say that's what will happen when you're playing back ACTUAL user content?
...it Doesn't, so you are ASSUMING it's the same result.
It most certainly is not, as many ACTUAL owners are trying to tell you
Most here can drive their Yamaha systems well over reference levels without the need for added amplifiers.
It's been happening for DECADES already, at least 4 for me.
If lack of power was a real world issue for REAL YAMAHA owners, there would be a sticky thread at the top of this page,
...right above the https://www.avsforum.com/forum/90-rec...il-2018-a.html
Just because this is all new to you, doesn't mean we haven't all heard it here already.
From Sound and Vision in 1988, one of my older AVR's ...an RX-V1800
...a page right out of your own Gospel:
In case you can't read the fine print it reads:
...Bettered 100 watts all around with 5 channels driven, it ran out of current when 2 more channels were added,
HOWEVER, SINCE the 7-CHANNEL RESULT DROPPED by 3dB
to 55 watts
- A NON-ISSUE IN THE REAL WORLD,
WHERE PROGRAM SIGNALS NEVER DEMAND THIS LEVEL OF STABILITY!
What Part of "NON ISSUE in the REAL World" do you not comprehend?
They are referring specifically to a SINE WAVE test load as being complete overkill,
you quite simply cannot
reproduce that in your own home, EVER!
I never had a lack of output power from my RX-V1800
MY RX-V3900 a couple years later was even slightly better...
...and both are still working fine today,
The RX-A3050 replaced the 8 y/o RX-V3900 this year for 4k, HDMI 2.0a, HDCP 2.2 upgrades
But most importantly for 11 channel processing Atmos/DTS:X in my Home Theater.
I ran my new RX-A3050 in 7 channel mode first and it performed even better than the previous models it replaced.
Powerful, Dynamic and Clean, even when expanding a 2 channel stereo to all 7 speakers to over 100dB levels.
The RX-A3050 currently drives my 7 bed layer speakers,
the old RX-V3900 powers the 4 Presence/Height Atmos speakers in Multi-Channel mode.
But the real bulk of the serious power in the room comes from
a Pair of 12" front subs and a Pair of 15" rear subs 1000watt/2000watt dynamic output each.
When that much Sub Bass power (below 80Hz) is taken away from the load on the AVR's power supply,
there is a DRAMATIC and very REAL increase in amplifier dynamic Headroom to handle all the easy-to-drive >80Hz frequencies.
Well above 100 watts per channel. PERIOD. Your 54watt SINE WAVE claim is completely and utterly moot!
You don't even have to be an electrical engineer to realize that.
