Yep, it proves your amp is still in working condition.The most important watt is the 1st watt.

I have the XPA-7 Gen 3, although it's only connected for 5.1 until I move to Canada. No issues, very happy with it.So, I've always been a standard AVR guy over the years. Always been intrigued by having separates, or at least....the beginnings of being able to have separate pieces. My current AVR is a Denon X4400H. I've been pleased with it, in general...though, when I really push the volume I always felt like it gets pretty screechy, and fatiguing.
Couple weeks ago, I purchased a Marantz MM7055 5 channel amp. I debated and debated, and finally did go with this as I got a really good price. It's 140 x 5 channels...but it's only 140 x 2 channels driven. Not all 5 driven. I didn't fully understand that until recently. So there is that.
My immediate impression was very favorable nonetheless. Having the separate amp truly did make a fairly big difference at higher volumes. That screechy detail was gone and replaced with substantial punch in my chest that was missing. Again, very pleased honestly.
In the end, I felt like this piece of equipment wasn't really suitable for future improvements necessarily. If, separates are the route I continue to go. So, I'm returning the Marantz, and already placed an order for an Emotiva XPA-5 Amp.
This amp will be rated at 250 x 5 channels, all channels driven. I feel like this additional power will be a good baseline for future upgrades to other channels. So, this will drive my main 4 Klipsch floor speakers and my Klipsch center. The 4 Atmos speakers driven by my Denon AVR for now.
Likely, in the future, I would buy an upgrade multi-channel processor and get more channels. Then, I could buy an additional amp, for those additional channels/speakers.

Just like all other AVR manufacturers (Except NAD), Yamaha only publishes 2 channel power output specs. Per their spec it is 150W, 2 channel performance, not all channels. RX-A3080 - Specs - Yamaha USAI have finally done my dream set-up for equipment. I have had a Yamaha RXA-3080 AVR(140 watts across 11 channels)
very strange that marantz specs it out at only 2 channel use when all other amp manufacturers (separates, not AVR) use per channel ratings. marantz are ok, but nothing great. marantz certainly is not what it used to be quality wise.Couple weeks ago, I purchased a Marantz MM7055 5 channel amp.

i have seen it speculated that tonewinner makes emotiva amps, but i'm not sure that is currently correct.I got the Chinese version of it and no probs yet!

attached is the manual, which shows a 2 channel power rating of 140w.I don't know where the info is about only 140 per two channels. The official read is 140 PER channel.
At hand this is really a power supply issue. At the risk of stating the obvious the power supply for the output power amp section can only supply, well, so much power. Probably with any two chs driven on this unit, front or otherwise, it will produce 140 WPC. But if you place test signal inputs on all 5 chs the PS will run out capability and nasty audio will result from clipping. Backing off the input levels willI don't know where the info is about only 140 per two channels. The official read is 140 PER channel.

fix the clipping problem but now the stated power specs will be quite a bit less. 75 WPC all chs driven? 100 WPC all chs driven? Hard to say with out testing but it would certainly be less.
Remember that when you use more channels, each channel needs less power to produce the same volume.Just like all other AVR manufacturers (Except NAD), Yamaha only publishes 2 channel power output specs. Per their spec it is 150W, 2 channel performance, not all channels. RX-A3080 - Specs - Yamaha USA
Rated Output Power (20Hz-20kHz, 2ch driven) - 150 W (8 ohms, 0.06% THD)
Realistically you will get about 75-90W when driving all channels.
With great power comes great responsibility.
The amp should only deliver power the speakers ask for. It's a pull situation, not push.That Emotiva amp can probably output twice what your big Uber-efficient Klipschs can handle. It will blow them to smithereens if you’re not careful. But it’s great to have the extra headroom.
I didn't check on Gene's rear speakers but his front RF-82 power rating is 150 W RMS/ 600 W peak. General wisdom is trying to play loud with an under powered amp for the situation invites clipping & that is more prone to (mainly) tweeter damage than simply playing loud. As you say with those Klipsch efficiency I imagine he will blow his eardrums out before he blows the speakers!!@GOS Those Klipsch speakers with a sensitivity of 96 dB are so much more efficient than my AR beasts (87 dB.) For the same acoustic output, I need about 10 times as much power as you do. My amps are rated at 400 wpc into my AR9’s, which is the manufacturers maximum recommended power.
