Used in a strictly 2 channel stereo set up, with fairly efficient speakers, is there any real world difference, sound-wise, between the two? Thanks.

Assuming you are using efficient speakers in a typical residential listening room (size, construction materials, doors, windows and furniture) there will be very little difference in the sound reproduced by either of those two amps. Emotiva has designed all of their amps to have have the same sonic signature. So, if the amp you are looking to buy will be used in a dedicated situation and won't be used for HT as well the UPA-2 will be all you will need. However, if you may be considering upgrading your speakers in the foreseeable future; or using the amp for HT in addition to stand-alone stereo service; or if you have a large room/open floor plan with openings to adjacent rooms you may want to consider using the XPA-2. The more detail you furnish us with, the better focused our advise will be. There are a multitude of factors that can influence the power requirements need for any particular sound system and the more we know about your listening habits, the genre of music you listen too, the equipment you will be using, the placement of your gear and the furniture in the room, the type of floor and wall coverings, the size, placement and number of doors and windows, the exact speaker brand and model number, etc the more likely you will get genuinely useful input from the Lounge Members.

I have an XPA-2, with JBL 150A, JBL 100 & AR2AX speakers, using a Sansui AU-517 as a preamp. There is so much power that I hardly move the volume control past 6:30. I was thinking about getting a UPA-2 to repkace the XPA-2.

I was thinking about getting a UPA-2 to repkace the XPA-2. You have me confused, now. You said you are looking for an amp for a 2-channel stereo stand-alone music system. Yet you list three different models of speakers... tilt! How many total speakers are you looking to drive... 2, 3, 5 or 6? Are you saying you have a pair of each speaker you listed? Will you be using all speakers at once? If so, are you wiring them in series or parallel? If you will only be using a stereo pair, which of those speakers are you looking to pair up with the amp? How large is your listening room? What are you listening habits? ...and so on and so on? I am sorry, but my crystal ball is broken. ;D ;D We need details to be of any help to you. Otherwise we are taking "blind stabs" at offering you solutions.

Sorry if I was a bit obtuse. One pair of speakers at a time. There isn't much difference in power needed w/the XPA-2 driving any of these. It seems that the XPA-2 is putting out way more power than I need, and I wondered if the UPA-2 was better suited to my needs.

There ain't no such thing as too much power If you already have the XPA-2 and like the sound, I can't see any reason to downgrade to a UPA-2 because it has less power. Just my two cents.
