I think this little amp will be out of production within a year. No way I can see that people are going to pay this price for so little power and subpar specs. Of course there are plenty of Koolaid drinkers so you never know. I feel Emotiva has lost it's way. While I disagree about the subpar specs, I do agree that it is probably going to be a limited run item. It definitely won’t make old audiophiles into class d converts but it’s definitely got a place in some systems out there. Lol, you know me... I’m about as far from a kool-aid drinker as you can get. If I had the cash kicking around I’d grab a pair of these to play with. |

It's a clone amplifier - not an Emotiva designed product - put in an enclosure with an Emotiva brand signature - BUT at a reasonable price compared to the rip off high end clones. An out of the garage company can throw one of these together and sell it. Hey, if it performs as good or better than Emotiva's A/B amps, then it is a winner, provided it does not interfere with other communication / audio type items in your house. Personally I think Emotiva has lowered themselves with this type of product.

Personally I think Emotiva has lowered themselves with this type of product. I’d really prefer something with a tube front end like the Rogue Audio Medusa Amps. Throw a 12AU(X)7 buffer in front of a digital module (inside the amp) and I would have been drooling. But we really need to hear how the amps sound before we slam them. I know at Naim Audio they think the LED and switch even contribute to the overall sound. |

This is another in a great solution for those who need some power in a smaller form factor. This is a great solution whether in the studio or in a desk audio system or even a surround or zone 2 amp for instance. Tough to go wrong here. Is it for everyone? Nope nor does it have to be. But if you have an application where small and light is it. This is a great solution. Yes I have heard the Wryd 4 Sound. Nice but not ever going to pay that kind of money. I think Emotiva might have a great niche amp like the A100 Bas-X is. I can't wait to check out the PA-1.

ICE amps will have far more in common than glaring differences. The ASC module is well known and popular among builders taking the 'module installer' route.
I owned ASP amps years ago, in a dual mono 'integrated but eventually found the sound wearing.
I think VC, above, has a good take. The word is 'niche' whic might apply

I really would like to hear these amps. I think in the right application, they could be an excellent solution. In fact, I would actually like a version that is stereo to power my pool speakers (no need for monoblocks there, and 1 power cord beats 2 for limited use).

Here is a link to the ASC200 DataSheet. This is for all you 'specs' guys out there. However, ONE or TWO worrisome points. FTC Power is a fraction of the 200 watts 'listed' Heatsink is the real problem, even at such high efficiencies. Frequency response falls off right @ about 20khz. This gets worse as impedance drops. This causes phase problems in the upper frequencies where it is most audible. The ASC300 will be much the same. sound-power.ru/files/doc/ICEpower200ASC_Datasheet_20.08.pdf |

I'm anxious to hear how these perform. There was plenty of interest in an "Executive" system some years ago when the DC-1 debuted, and it was always going to be Class D based on the form factor.
I may buy a couple, but they'd be to compare again the XPA-100's in my bedroom system, since I leave that system on all night.
I already have plenty of spare (backup) gear, so still on the fence about when to purchase.

What is the difference between ASC and AS1 models? I'll be they sound identical.
As for someone above, asking about capacitance? Nearly irrelevent on an amp with SMPS. A conventional PS running at 50hz or 60hz will recharge the PS caps at the line frequency rate and ONLY when the PS
voltage is above the capacitor voltage. So when under very LOW loading? Caps recharge only at the TOP of the sine wave.
For a Switcher? Those opportunities happen much more often, based on the swithcing frequency of the PS. 100khz? 200khz? 400khz? You'll need to ask someone. Becasue of that, you simply don't NEED
to store huge amounts of power.

Great job Emotiva on the introduction of the Icepower PA-1 amp! I think it is great that Emotiva has joined the club of Icepower amp providers. I built my own mono blocks a few years ago based on earlier Icepower modules and they work great. I will definitely be picking up a a pair of the PA-1's to try out as well. -CB Here's my home built Icepower amp on the "test bench" aka my kitchen table!  Attachments:

Good work and a nice roomy layout.
How'd they work? What was your start module? Why not Hypex?

Good work and a nice roomy layout. How'd they work? What was your start module? Why not Hypex? Case and wiring came via China by Ghent Audio. Icepower modules were from either ebay or parts connection. Some Icepower modules I have bought were pulled out of salvaged subwoofers. It's unfortunate that Icepower modules are not typically sold direct to the consumer since it is relatively simple to assemble these amps. Having said that, the Emotiva amps at $299 are a very good value and I wouldn't hestitate to purchase. -CB |

Well, they're "cute", but I think my money would be better spent on the BasX A-300 and pocket the extra $200 I would save.

I heard that the assembly area for the PA-1 amps is comprised of 25 kitchen tables.  |

Having said that, the Emotiva amps at $299 are a very good value and I wouldn't hestitate to purchase. -CB My personal bias is to go with HYPEX, which is available to normal people. At least the UcD line and the nCore400. Other amps in the nCore series are OEM, only. I had an ASP integrated many moons ago, the 500x2 version (middle of line) which drove my panels just FINE. But once the new wore off and I did a Detailed setup, I found the presentation lacking. Something to do with the HF and it being 'phasey' at the same time. PSAudio Gain Control input section was wonderful and had 1 set of balanced 'ins'. ![]() I've noodled up (block diagram) of a dual nCore 400 mono amp with a MiniDSP and 2 amp modules and the large SMPS. This amp would be meant for 2-way (3-way w/Sub Out) powered speakers. For my 0.05$ that's the real leverage of the 'D' amp. Even low-sensitivity panels, like my Maggies would be eligible. For the DIY guy? No Limit. What module were you able to purchase? The real thing or 'counterfeit'? Attachments:
