Pound for pound and dollar for dollar, it's the best amp in the lineup!!!
not too much heat in A/B mode, but for two channel ,,,,slide it to Classe A 

I will only use it for two channels. Does the 1L's heat like the heat of XPA 5 if it is on class A mode?

Hi rod, no, the -1L does produce more heat then the XPA-5 but, I use my -5 for center and four surounds and not driving my main speakers. So, the XPA-5 would produce more heat driving a two channel system. That said, if ventilated I wouldn't worry about the heat.

I do think a little more heat is more then worth the advantages of these MONOBLOCK s.  8)

I'm on my second set of XPA-1Ls, I was foolish enough to return my first set,,,,I just didn't realize at the time how great they were. I now know, and I DO own a set of XPR-1s, I think that speaks volumes!!!

That's just Emotiva being Emotiva It doesn't look like there's any difference between the old and new amp. Just cosmetics.

Hey, I wont forget you because all the advice you gave me then and now is really helpful. I learned from you that DC-1 is great then I bought one to replace my one month old XDA-2 and a lot more. What's more, you told me something like this the other day that it is unwise to purchase XPA 1 for my current set up since it XPA 2 will do the same thing and that's really right. But what do you think about this new amp, 1L? Will be the perfect match for my LSI15 because my current XPA 2 with will be connected to my LSI9 instead?

Hi Rod. I remember you well! Glad to hear you are enjoying your setup!
The LSI 15. Well that's a different beast eh? Will you be using it with your DC-1 and other gear? What will the XPA-2 be connected to?
Now be forewarned the XPA-1 L will run hot. That's normal operation for it. If you don't like it, then it's not for you. I actually heard the XPA-1 L connected to a set of axiom m80's.
They are nice amps. I can't promise they will be an upgrade over the XPA-2 as I didn't hear the XPA-2 with the same setup at the same time. It's been some time since I heard the XPA-2.

If you have the money, maybe some used big brother XPA-1 gen 1's may be a better upgrade. The XPA-1 L may not be an upgrade as the XPA-2 is really good. But a user called geebo upgraded from an XPA-2 to XPA-1 L and found it worth the money.
So the honest answer is I don't know which one would be an upgrade. But if you HAVE to buy an amp, an XPA-1 L is a very nice piece of work! (And so is the big brother XPA-1 used or not).

I have my 1L's stacked with a C-12 fan between them it keeps both cool even running in A mode. The 1l's are GREAT amps!

I currently have an XPA-3 Gen 1 that powers my L/C/R; run the surrounds and front heights off my Yamaha 3040. Have considered getting XPA-1L's for the L/C/R instead - would I see (hear) much benefit over the XPA-3?

[geebo]

The XPA-2 and 1Ls are both very very good. You would not be disappointed with either. I'd have to give the advantage to the monoblocks but as mentioned above they can get a bit warm especially in A mode so make sure you can provide them adequate ventilation. I would not be disappointed however, if I had to go with an XPA-2.

In my opinion, yes. Better dynamics and awesome impact.

This is very good advice. The 1Ls DO run pretty warm, even in AB mode. That is important in many instances and was for me since I also run tube amps. In the end, XPA-1 Gen I were a better fit. Twice the power and cool as a cucumber.

Peace

I think I will go for XPA 1 either gen 1 or 2 even thought I don't know the difference between the two. I did a little calculation and found out that the difference between the current prices of 1L and XPA 1 gen2 with ecard is $750. What do you think?

If the difference in the coin is not a problem, there is no question as to what you do, enjoy the 60 watts of Classe A as well as all the head room!!

youll love the sound!

Wish Emo would make more C-12 badged as their own, just have to find a way to keep the price point down!!!

Two XPA-1Ls Gen 2 on the way!!!!!!!!

I just read the secrets xpa-1g2 review. I didn't know that the Class A output at 4 ohm was half that of 8ohm. Im assuming this is true for the 1L also? Would that mean Class A is limited to 17W @ 4 ohms? The new price is a surprise. I was expecting a significant price hike like all the other gen 2 pieces. It makes it even more tempting.

Well the reason I reccomended used gen 1's pair is that they are the same price as a pair of new XPA-1-L.
The XPA-1 gen 2 does bring about significant class A power (120 watts in stereo !!) which eliminates a certain type of distortion called crossover distortion when it is in class A mode. I can't think of any other amp in its price range that can do everything it does.
In stereo:
120 watts class A
2000 watts @ 4 ohms (!!)
Monoblocks
Fully differential
Over 200,000 mf of capacitance
2.8 KV of power supply.
It's pretty insane.
Try getting that with an integrated amp!

But...having said that. Is it worth the cost increase for the sound quality it will bring you? I mean that's a LOT of money.
For instance, you could buy two very good subwoofers for that money like these.

Since you already have the XPA-2 - which is a nice amp, I don't know if it will be worth it for you. It might be. Or you may not hear a difference. It's not my money, so I hesitate telling you what to do for sure....because you already have a fine amp. I'm not saying there won't be an improvement! It may sound FANTASTIC for you. Just that I don't know either way.

I skimmed through that a while ago, some of it was well over my head, the following quote was interesting though.

"The XPA-1 design causes the performance in mode Class A/B mode not to be optimized. This is the result of including the Class A biasing option. It is possible to have both Class A and Class A/B optimized, but this requires extra circuitry not in the XPA-1"

I'm not sure what they mean by optimized, but as a side note, their review of the original XPA-1 gen-1 stated that at 1% THD the XPA-1 produces 680 watts into 8 ohms and 1100 watts into 4 ohms.

I don't know where the "XPA-1L's get hot in Class AB" claim comes from but I have had 2 in my system over the last month and neither of then ran any hotter (pyrometer readings) than my XPA-100 doing the same work The XPA-1L's do run a little hotter in Class A but they sure as hell have the heatsinks for it.

Mine definitely run warmer in AB mode than my XPA-2 did.

Anyone confirm the half Class A power when at 4 ohms??? I thought 35W=35W no matter what the impedance in Class A...

It's 35 watts in Class A regardless.

Yeah, thought so. Thanks.
