That's correct, the XA30.5 is rated at 30 watts Class A @ 8ohms and 60 watts Class A @ 4ohms. After that they are Class A\B From the XA30.5 spec sheet: XA30.5 / Specifications Gain (db) 26 Power Output /ch (8 ohm) 30 Power Output /ch (4 ohm) 60 Input Impedance,(Kohms) 30 / 20 Leaves Class A @ pk Watts 60 Power Consumption (W) 200
Nelson Pass quoted in May 2009 Stereophile review of the XA30.5 but really talking about the XA.5 architecture: "At higher levels, both n and p devices contribute to the output as a push-pull pair, operating in class-A mode up to the amp's rated output and class-AB beyond that point."

The Pass website states "the XAxxx.5 amps are Class A for their full rated power into 8 or 4 ohms". For $270 per pound of weight...... They better be Class A. Or include a small gold bar. Or both? ;D The components certainly don't cost what the MSRP prices are. Even the lowly XA30.5 costs 7 times as much as the XPA-1L. Disclaimer: I'm sure the Pass amps are good. Just too rich for my blood. I imagine the high end market and distribution network sets the exceedingly high price point. "It's expensive, so it must be good". If it were cheaper, it wouldn't be as exclusive. I just can't wrap my head around what makes an amp cost $31k.

[FEDEX Estimated Delivery: Monday 3/18 Ah, nuts. It's gonna be a long weekend for you. There are good reasons for living on the West Coast. Being really far away from Emotiva is not one of them. Disclaimer: I'm sure the Pass amps are good. Just too rich for my blood. I imagine the high end market and distribution network sets the exceedingly high price point. "It's expensive, so it must be good". If it were cheaper, it wouldn't be as exclusive. I just can't wrap my head around what makes an amp cost $31k.Agreed. I understand the markup (in several places) impacts the final price, but I'd much rather buy an Audi A4 or an Acura TL for $31K. In other news, it looks like FedEx will be delivering my 1L on Thursday. I hadn't planned on getting the amp until next week, and the additional rack shelf doesn't arrive until Friday, so I won't be able to set it up permanently until Friday afternoon. I need to schedule a Hold at FedEx Location for the amp since I won't be around to sign for it on Thursday.

Well mine is supposed to be here Friday. I bought a new rack that will help these stay cool by not stacking them, and that won't be here till next week though. Crap! I probably won't be able to play with them for a week!!!! Edit: Sorry Dark Ranger, I didn't read all the way through your post. Seems we are in the same predicament! Guess it's a good predicament though since they weren't supposed to ship til Fri anyway. i like the nakamichi wave flex banans with the double screw.. the new wave flex design really gives much better contact that you can really feel during insertion how much tighter it is.... cheers Couldn't agree more! Normal bananas do not have much contact area with the jack. The "wave" bananas are excellent IMHO.

Question:
These babies are supposed to run warmer than a similar A/B amp, say an XPA-100 or an XPA-2 or even an XPA-1. Then why does the "L" seem to have a lot less vents in the cover? Look at the pics of each amp on the amplifier page.

Checked FedEx and my amps missed connection by less than an hour for the truck going to Little Rock, Ar. Now it will be Thursday, still better than the March 15 ship date Emotiva posted earlier on their web page. I just purchased a Sherbourn Pre-1 to put with my Vincent Amps and move the XSP-1 to the XPA-1L Amps. Didn't need to spend $899 on another Pre and Sherbourn was balanced and on sale.

From our friends at Audioholics: www.audioholics.com/reviews/amplifiers/emotiva-audio-xpa-1l-pre"If you've wanted to experiment with a Class A amplifier but didn't have the thousands it normally takes to step up to that level, the Emotiva XPA-1L is for you. With selectable Class A/Class A/B operation, it has something for everyone. Putting out 35 watts in Class A mode and 500 watts (4 ohms) in Class A/B mode, it should pair well with nearly any speaker you may own. We are also wondering if Emotiva is planning on implementing this Class A switch to their entire line of Class A/B amps. It would certainly help differentiate their offerings from all the other Class A/B amps out there. We are definitely looking forward to getting the Emotiva XPA-1L on our test bench." (Let the rumors begin!) ;D

Actually, that's sort of an odd thought..... A real digital speaker would probably be connected via Ethernet, or USB, or Toslink... Oh, digital spade lugs.

Heck these guys haven't even done a review of any of the XPR's yet. It might be a very long time before they get to the XPA-1L. I also found this statement rather stupid: "We are also wondering if Emotiva is planning on implementing this Class A switch to their entire line of Class A/B amps. It would certainly help differentiate their offerings from all the other Class A/B amps out there."As if it's simply a matter of adding a switch. Yep the XPA-1L is simply an XPA-100 with an additional switch. Please... . ...

Here's how it works.... In Class A mode, the XPA-1L is Class A up to 35 watts. In that mode, in the range between idling and putting out 35 watts, the XPA-1L draws about 200 watts, about 2/3 of which is dissipated as heat (so we're dissipating about 130 watts as heat). In comparison, in that same range, either the XPA-1L in Class A/B mode or the XPA-1 would be about 60% efficient, and so would be dissipating 25 watts or so - and so would run much cooler. As we go above 35 watts, and the XPA-1L transitions into Class A/B mode, its efficiency approaches that of the XPA-1 (or its own efficiency in Class A/B mode). At anywhere near full power, the XPA-1L will be running only slightly warmer in Class A mode. Since the XPA-1 is twice the power of the XPA-1L, at full power it will still be making a lot more heat than the XPA-1L ever does in any mode, which is why the XPA-1 needs more vents. The point is that many people really run their amps at a few watts to a few tens of watts most of the time and, over that range, the XPA-1L in Class A mode will run toastier than either itself in Class A/B mode or the XPA-1. You shouldn't worry about it; but do be sure to give it a bit of room to breathe. Note that the XPA-1L will NOT get excessively or dangerously hot (it won't ever exceed the CE safe case temperature limit), it's just that it will run warmer than you are probably used to for our other amps. ;D Question: These babies are supposed to run warmer than a similar A/B amp, say an XPA-100 or an XPA-2 or even an XPA-1. Then why does the "L" seem to have a lot less vents in the cover? Look at the pics of each amp on the amplifier page.

In case anyone hasn't noticed, the 1L manual is online along with the AP reports! ;D EDIT: read manual and AP reports - check! At least that's out of the way. Now I can proceed with the next step, hooking up the amp. Wait a minute, did the manual say to connect the left speaker output to my left ear or right ear? I use a digital TOSLINK for the amplifier input, right? How do I turn it on? Will there be unicorns coming out of my speaker when it sounds good?

Question: These babies are supposed to run warmer than a similar A/B amp, say an XPA-100 or an XPA-2 or even an XPA-1. Then why does the "L" seem to have a lot less vents in the cover? Look at the pics of each amp on the amplifier page. I noticed that too. It took me a few seconds to figure out what was different when the image first went online. After careful comparison to the internal pic, I noticed that the vents are strategically placed above the heatsinks and other critical areas. That said, it's still curious why my XPA-200 and UPA-500 have full venting along the top and will never produce as much heat as the 1L will. Not too worried about it since the 1L passed testing and such, it's just a curiosity to me. Thanks for the link, Jim! I love some of the follow-up responses: *sigh* I do have to agree with ocezam regarding the Class A/AB switch on all Emotiva amps. There is a lot more to the 1L than adding a switch. Let's not forget that most of the Emo amps run <1 watt in Class A, so it would be kind of useless in my opinion to add it to other amps. For the 1L, it makes sense and should be one of the selling points. I probably wouldn't purchase a pure Class A amplifier, but the hybrid 1L gives me the best of both worlds depending on my preference. In my opinion, I think the 1L is going to shake up the industry and bring even more new customers to Emotiva. Of course, some will continue to discredit Emotiva for other reasons. Yeah, I'm a fanboy, but there are compelling reasons for my loyalty.

Looks like they increased the specs on the SNR.
