Just in case you do decide to go down the Atmos route one day with the AV-7702MkII.
Yeah, that is an intriguing unit. Curious as to how it will stack up. Unfortunately, Atmos I won't be in the cards for several years. My HT is currently in my living room, which has 20' ceilings. Modules won't be any use, and installing speakers that high probably won't be that effective either. I'm going to finish the attic space over my garage at some point and move the HT there, but the wife wants a pool first.

The 3rd generation of XPA amps are now available from Emotiva here: https://emotiva.com/products/amplifiers/xpa-gen3

The 3rd Gen XPA amps are build to order and based on the number of channels needed. Basic price of $899 is just for 2-channels in classic "solid" stereo mode. Note that maximum power is limited to what can be driven into 2-channels. The 3rd Gen XPA amps are now rated to drive 2-ohm loads.

Comparing the MSRP price of the 2nd Gen XPA-5 vs. 3rd Gen XPA-5, there is a cost increase of +$500. This is based on MSRP of the 2nd Gen XPA-5 being $999 vs. 3rd Gen XPA-5 being 899+600=$1,499

The increase in costs from 2nd Gen to 3rd Gen gives you a Class H type amp, switch mode power supply (lighter weight) and an additional 50W per channel.

Anyone willing to try out the new 3rd Gen XPA-5?

Class H, not G, according to their datasheet. Class G switches the power rails among different voltages based upon the input (and thus output) signal; class H uses a tracking power supply to follow the input. The basic amplifier is still class AB.

Come again?

The max power is limited to what can be driven into 2 channels? Does that mean what I think it means, that the multi channel amps can't make rated power to all channels at the same time?

Their description and specs:

A Word About Power Ratings

Music is, by its nature, dynamic. While it’s relatively common for the two main channels in a stereo amplifier to be asked to simultaneously deliver high
power levels, it is very uncommon for more than two channels to be called upon to deliver high power continuously at the same time, and this almost
never occurs outside of laboratory test conditions.
In order to deliver the most dynamic performance where it counts - with real music - we have designed the XPA Gen3 modular power amplifier with a
single immense power supply, which is able to deliver massive power continuously to any two channels, and to deliver huge amounts of power dynamically
to any number of channels when and if called upon to do so.
The power ratings for the XPA Gen3 modular power amplifier are the same with both channels driven continuously in the two-channel version of the amplifier,
and for ANY TWO CHANNELS DRIVEN CONTINUOUSLY in the versions of the XPA Gen3 configured with three, four, five, six, or even seven output channels.
In addition to this, because we always aim to provide the most complete information possible, we have also rated the other versions in terms of continuous power
(under laboratory conditions) with all channels driven.
Also note that, while the exceptional sound quality of the XPA Gen3 modular power amplifier, and its two-channel continuous power rating, remain the same
whether you choose to use a 120 VAC line or a 230 VAC line, the multi-channel power ratings are somewhat higher when you power the XPA Gen3 from a 230 VAC circuit.
While the XPA Gen3 modular power amplifier will provide plenty of power for most home theater installations when run from a 120 VAC line, for the absolute
best possible performance, we recommend operating the XPA Gen3 from a 230 VAC line.
Circuit Topology

A fully modular audio power amplifier with a high-efficiency switch mode power supply (SMPS), independent, fully discrete, dual differential, high current,
short signal path Class A/B amplifier modules, Optimized Class H™ power supply topology, and microprocessor-controlled fault protection.

Power Output
ALL MODELS: Power Output Per Channel
300 watts RMS per channel; 20 Hz - 20 kHz; THD < 0.1%; into 8 Ohms
550 watts RMS per channel; 20 Hz - 20 kHz; THD < 0.2%; into 4 Ohms
800 watts RMS per channel; 20 Hz - 20 kHz; THD < 0.5%; into 2 Ohms
ALL MODELS: FTC Rated Power; 2 Channels Driven; 20 Hz - 20 kHz; THD <0.1%
300 watts RMS per channel; THD < 0.1%; into 8 Ohms (120 VAC line).
490 watts RMS per channel; THD < 0.1%; into 4 Ohms (120 VAC line).
Power Output Per Channel: All Channels Driven; THD <0.1% ; into 8 ohms


XPA two Gen3: 300 watts RMS per channel
XPA three Gen3: 275 watts RMS per channel
XPA four Gen3: 260 watts RMS per channel
XPA five Gen3: 250 watts RMS per channel
XPA six Gen3: 225 watts RMS per channel
XPA seven Gen3: 200 watts RMS per channel


To me.... while the type G power switching is more efficient and allows for using a slightly smaller power supply for driving multiple amp blades (esp 5 & 7) it is still governed the total available power, they simply chose a power supply that would give you 200 w/ch with 7 channels driven and anything over that for less channels driven is just gravy.

Yeah, I'm not sure what it means either. But if the XPA-5, which is rated by them at 250 wpc, can't do 250 with all channels driven, then they are playing with the numbers. Maybe it can do 200 x 5, I don't know.

Did you get the new Generation 3 or the older Generation 2?

I got the Gen2. Wanted to start off with this amp since it has a good reputation.

Yes, I had seen that. My understanding, and please correct me if I'm wrong, is that those numbers are for 2 channel continuous power rating of each amp.

XPA5 Gen2 came in last night. All hooked up to my 5.2 system consisting of:

PreAmp: Pioneer Elite SC-65
Source Player: Sony BDP S790 Bluray Player
Speakers:
Sonus Faber Venere 2.0 Bookshelves(Fronts) - 88dB / 6-Ohm / 200W
Sonus Faber Venere Center 89dB / 6-Ohm / 150W
Definitive Technology ProMonitor 1000 Bookshelves(Surrounds) 91dB / 8-Ohm / 200W
SVS SB-2000 Subs (Dual Setup on front stage)
Cabling: Monoprice 12AWG CL2 Speaker Wires, Monoprice HDMI Cable(6ft), Mediabridge RCA Cables(4ft)

Music demo'd so far:
Tommy Smith "Peace and Love" CD
Michael Jackson "Thriller - Special Edition" CD

Movies demo'd so far:
Transformers: Revenge of the Fallen Bluray
Avengers Bluray
Spectre Bluray

Initial Impressions:
- Sound seems more dynamic at low to medium volumes in both Stereo and Multi-Channel playback.
- Heat dissipation isn't bad.
- I have not noticed any "hissing" sounds from my speakers.


Will post more of my perceptions on this amp for those people still on the fence. I consider myself have novice to intermediate knowledge in this hobby. For those that this may relate to.

More review:

Set SC-65 Amp to OFF. (Yeah, finally found the setting.)
Speaker Settings set for: Normal setup, distance set, phase control and standing wave. EQ set to OFF.

I re-watched Transformers: Age of Extinction in 3D, 5.1 TrueHD. First of all, I am not a big fan of the movie, but this series is just great to demo and test a system.

Believing that being forgiven would be better than asking for permission, I played the movie at my "Blockbuster Movie Night" level while my wife was still in the house. Before these parameter changes and the amp, she has complained about the volume level that I listen to. This past weekend? She had no complaints. She still had our bedroom door open and only had the TV's volume up a little louder that usual. Wow! I will continue my audition throughout the week and this coming weekend. About mid next week, I will go back to the previous setup to ensure I'm not "hearing my enthusiasm".

However, so far so staying home.

There are never failures, only challenges.

Decided to bite the bullet and ordered an XPA-5 yesterday. I was planning on waiting a little longer before picking up another amp but after seeing all the other Gen 2 amps disappear from their site over the past few months, it seems inevitable that the 5 will be gone soon too. I'm also just not motivated at all to spend over $500 more for the Gen 3 version. If that was my only choice, I'd probably just go with the Outlaw 5000.

I was really only in the market for a three channel and was leaning towards the XPA-3..until it disappeared. I have a UPA-2 already and only a 5.1 setup right now and the UPA-2 provides plenty enough power for my mains. I was going to use the 3 ch amp to power my center and two surrounds (or maybe the front 3 and then put the UPA-2 on the surrounds.) I do plan on upgrading to a 5.1.4 setup later this year so both amps will still go to good use.

I'm specifically looking forward to watching Tron: Legacy with the new amp as that's the only movie I've seen which actually caused distortion in my surrounds during a few scenes. The soundtrack (and sound effects) to that movie are really incredible. Too bad the movie itself is only so-so. My surrounds (and center) are currently being driven by my Onkyo TX-SR706 (very outdated, I know) and it just can't handle it.

Looking forward to the new amp.
