Based on what we learned about the XPR-7 at Emofest, it would be hard to believe that the XPR-2 would possibly have less than 500 W/ch into 8 Ohms. The podcast stated that the XPR-2 would have a 3 KW power transformer. Do the math. The XPR-7 was stated to have a 3.5 KW transformer for 7 channels and was testing out at nearly 370 W/ch at 8 Ohms. It would be very hard not to expect 500+ W/ch at 8 Ohms. If it is really coming in less than 500 W, Emotiva has intentionally made a decision to limit its power output. With the XPR-7 Big Dan was advising that anyone buying it have a 230 V circuit installed to power it. Maybe Emotiva decided to limit the power output to allow using 120 V circuits to power it. Then again, being the "'premier line" of amps, the XPR's needing 230 V circuits may be an acceptable caveat. ;D Food for thought... Well, since I compared the XPA-2 to the UPA-1 I know that this is not about power but about the better concept. So I really wonder what all this power is going to provide, hopefully not only power but also a musical amp. By the way: 3 kW must be a mistake. If an XPR-2 with a 3 KW power supply comes out t be only 2x500Watt this would be all but efficient. Aside the fact that it is not very sustainable either but that is another story. So I am really anxious to read the first reviews about these XPR series. What I missed was a word about the XSP-1 that I am looking for. Hopefully this project is still alive...

By the way: 3 kW must be a mistake. If an XPR-2 with a 3 KW power supply comes out t be only 2x500Watt this would be all but efficient. One "all but efficient" design approach uses a high level of bias to get better sound quality. Such amplifier designs are usually called Class-A. I don't know anything more than you guys about the XPR-2, but perhaps the XPR-2 ups the bias to deserve its "reference" status and 3kw transformer.

It depends on the design. A typical Class AB Amp has about 60-65% efficiency overall which would bring it in at around 2000W max. This would probably be at 4 Ohms which would be around 500W at 8 Ohms.

I'm surprised more people aren't talking more about these new XPR amps. Many are interested and many are puzzled. Emotiva has such a large offering of amps. Look at all the choices for 2-channel people. Do you want 2 channel or monoblocks? They have several for you to choose from at different price points. I've been looking for a senseless reason to upgrade my RPA-1s and over a year ago when Lonnie mentioned an RPA-2 successor where we won't be disappointed. The XPR-2 certainly sounds like it won't disappoint, but can it topple the XPA-1 as a new flagship? With so little detail and without a release and without final specs, those interested like me probably are just waiting for the facts to roll in. And waiting is always the hard part... Luckily what I have now is not disappointing so I am looking forward to it's successor.

I do wonder if Emotiva is producing too many products; especially considering that the price differences are really not that big in absolute terms...

Haven't seen a lot of come out of this thread?? I just wanted to reinforce how fast I would sell my XPA-2 and 3 for XPR's if they had analog meters. BIG analog meters. I don't think I could type fast enough to sell them for those babies Anyway Emotiva, I know your busy, but I just wanted you to know that you would have 2 more sales with analog meters Enjoy your weekends

I wish Emotive would just finish some of the products in the pipeline that I've been waiting patiently for for years!... before going nuts on yet another AMP!

Well put Someone asked previously why there wasn't more discussion of the new line of amps..... I think most of us have learned about "timelines" with up coming Emotiva products. And Emotiva has learned not to promise as much as they have in the past. Mums the word....Just to be clear, this is not a bash, just an observation. I will continue to purchase Emotiva amps as my system grows. Waiting on the DAC right now. ;D

I just took delivery on two xpa-1's ... I bought them for the better quality instead of the over kill power.
Please don't tell me there is a better quality amp comming out!

I would also love BIG BLUE METERS but it would truly break my heart to sell the RPA-1.

No worries, like the Audiocritic wrote when he tested the Benchmark DAC1 PRE that you have: "you can't outperform perfection"... I presume the XPR-2 would be like 2 XPA-1 in 1 box. Mono-blocks are still king as 2 channel solution. If there would be a XPR-1 on the other hand ;D

I'm tying to burn the amps in and let my ears adjust to them a bit. I'm used to Krell so I'm having to adjust to a slightly different sound. I'll have a better sense of their character once they have been burned in and my ears adjust a bit. I still want to see what I can find on the new amp so I guess I need to search the forum some more.

The XPA-1 is a Class A/B amp while the XPR-2 will likely be Class G (like the RPA-2) or Class A if we are lucky. Mark.

I don't know of many (any) Consumer Audio brands who use Class G... D is efficient, B is rare, A/B is standard and A is supposed to be the best...

The XPA-1 is a Class A/B amp while the XPR-2 will likely be Class G (like the RPA-2) or Class A if we are lucky. Mark. That kind of power in Class A is not realistic. There are amps that are selectable between 300W@8ohm in AB or 100W@8ohm in A. According to the reviews I read about Class A, there are no better sounding amps than Class A. Downside in these Eco-aware era is the matter of the power consumption (100W really uses 100W, unlike Class A/B) and the heat production of Class A. I thought it (the XPR-7) would have a Class H (variable) power supply, but the respective amplifiers are normal A/B. I suppose the XPR-2 is the same design as XPR-7&5? And the XPR-7 is shown with the same meters (dots) as the XPA-series, but vertical, so any hope for analogue meters seems idle... And the price of the XPR-2 is going to be lower than a pair of XPA-1, so again, I can't see why it would be superior. As a series ofcourse, the XPR ("R" from reference?) will be "flagship". I want a XPR-7 for my homecinema! I am lucky enough to aim for a separate 2 channel HiFi (living room, upstairs) with the monoblock XPA-1 and the Jamo R909 I have. So the homecinema can be aimed @ watching movies & music video for which purpose I believe in amps with huge but shared power supplies (XPR-7), unlike 2 channel, where separation is king (XPA-1)

Have we seen a price for the XPR-2 yet? I do have to correct you on one thing. The RPA-1/-2, MPS-1/-2, and presumably the XPR series do not use shared power supplies. Each channel has its own power supply. That is why the RPA is called a dual monoblock. Each channel is completely independent. And there you see a potential for cost savings. A pair of XPA-1s are housed in two chassis, whereas an XPR-2 is in one. Mark.
