The XPA-2, probably not, unless it is the same module run at a little higher voltage, and I also doubt the XPA-1 uses the same module as the other amps in the line. I imagine the circuit topology is the same up and down the line with the possible exception of the XPA-1. Of course power supplies vary, but movies and music rarely if ever drive every channel to max at the same time, in phase, and all that jazz so I doubt I would hear the difference. I don't usually pay a lot of attention to the power supply unless it is exceptionally large or small.
XPA -3 has a smaller power supply than XPA-2. I can't see how that is good.

Isnt the XPA-2 designed for 2 channel usage, meaning running full range fronts potentially for music? I would expect it to be beefier.

The XPA-3's main use is running the fronts, letting an AVR power the rears, for 5.1. That was my main reasoning for getting the XPA-3, because I know it outperforms any AVR.

And then if you want to run 7.1, you buy the XPA-7. I see them all as having a particular function.

Why would you think someone with a 3 channel isn't into 2 channel? You just select 2 channel. I'm using a 3 channel amplifier and I play back 2ch music.

Thats not what I meant, but the amps (looking at specs) have an obvious target that I think you are missing. Thanks as well for the explanation of how you play 2 channel with a 3 channel amp, I was unaware it was that easy...

I personally think the XPA-3 could handle 2 channel music fine, but the XPA-2 is beefier for a reason in my opinion.

XPA-2 is more $$$ too. Also note their descriptions:

XPA-2 = "
Stereo Power Amp
Legendary two-channel performance.


"

Even in the description the XPA-2 (for movies) is focused on powering fronts and letting the XPA-5 power your other speakers. This is goofy to me, just buy a XPA 7. I do know some people like a dedicated 2 channel setup, and this amp would be great for that.

XPA-3 = "
Three-Channel Power Amp
Supercharge your home theater.


"

My take on their line is:

XPA-2 - perfect 2 channel amp for music; could also couple with a XPA-7 for 9 channels

XPA-3 - perfect amp for someone who runs 5.1 with a good AVR and wants more power where you need it, in the front 3 speakers

XPA-5 and XPA-7 - Amps built for 5 and 7 channel HT systems and of course music.

IMO, if I was buying any of their amps for HT AND music, it would not be a XPA-3, especially with hungry speakers. Id opt for the 5 or 7. But you take from their model line what you will. I personally think worrying about the XPA-3's lower capacitance and smaller transformer is a waste of time. I run a 3.2 system for tv and movies, but do listen in stereo and 2.2 basically. XPA-3 sounds outstanding, but my speakers are also very efficient. The sound is more open when cranked than my 4520, so I got what I wanted.

The problem I do have with their numbering system is, the layman may think they are all created equally with just more channels, but that is not the case with these XPA amps and you need to think closely before buying.

When we move, Ill be buying an XPA-7 for my HT room, and leave the XPA-3 and the 4520 for the TV room.



And no, I'm not jealous of your speakers...

Other makes scale up the power supply as the channels increase.

They do seem to cut corners. If the XPA2 has something like 1200va PSU then XPA3 should have something like 1600/1800VA.

I second this it almost seems you would benefit with using all xpa2 than the others plus the xpa2 you could bridge and really cook something

I have a new XPA-5 in a closed cabinet with 2 inches clearance on sides and top powering 2 Goldenear 3 speakers +1 Goldenear Center, all running full range + MK Tripole sides (4ohm). I cool my amp with 1 AC Anfinity AL-MPF usb computer fan. Amazon 14 bucks. After 2 or 3 hours of hi dynamic movies the top of my amp is stone cold.

Been nice to know that when it was still at $888, that would have made for a heck of a deal with the membership discount. I may have to snatch it up with the discount. Thanks.

You could always wait for their spring sale... Or call/email them and see if they'll give you a break.
