Comparing digital amps

Who makes digital amps and what are the thoughts on them individually? I've searched the archives and here's what I found:

PS Audio
Bel Canto
plus Panasonic and Sony

I'm looking for a summer amp because my 100 watt tube amp is just too much for our AC-less summers. I'm curious about digital amps for several reasons including that they run cool. I'm looking for a good value, but would also like to hear about the more expensive units. I'm curious about the ability to run my transport direct into the amp (but I don't this can beat an Audio Note DAC). Most of these don't appear to be available for demo nearby. Any informative comments greatly appreciated. Thanks.
I am 100% elated with my innersound esl. It puts out 300wpc into an 8ohm load, is unconditionally stable into a 1/3 ohm load, and doesn't generate any heat. I don't even turn it off. Actually, I compared it to a Krell FPB-300, and it didn't fair badly at all. It has a very warm, tube-like sound. For the money, you can't beat this amplifier (~$2500).
Check this out Budrew if you haven't read it yet.It will give you a crash course on digital amplifiers and their differences.The audio note dac is a different technology.
One more to add to your list is Acoustic Reality. They have an amp for approximately $1500, that might suit your needs. I bought the PS Audio amp, in the same price range, because it has XLR inputs and the AR doesn't. AR has some bigger more powerful amps as well, check out their website also.
Budrew- If your goal is to run your transport directly into
the amp, the are two choices- the new Spectron MIII and TacT S or M2150. I've had both the older Spectron MII and TacT M2150 in my system. The Spectron MII has enough power
to drive just about anything out there and is very smooth
with excellent control. The TacT has alot less power(150 vs 500),but a bit more ability to present inner details. Not having heard the MIII, I don't how it's digital and analog inputs will compare to the TacT's. The Spectral gets a little bit warm to the touch(nothing compared to a regular amp), the TacT can be left on or run hard and barely gets warm(like you no AC; heat reduction was one of the main reason I tried these amps).

With your speakers the TacT should more than enough power,plus you can eliminate your preamp and the DAC. If you're interested check out the TacT forum- There's
also a reviews of both amp on
If money matters you can't beat the CarverPro ZR1600 for about $840. Many have commented about its good sonics so I won't repeat that. This is one you can afford to try amd form your own opinion.
You can Audio Research, Jeff Rowland and B&O to the list.
You can add Linn to the list.
Digital looks like a freight train that could dramatically change the solid state amplification landscape.
Drubin, that train might pick up a few tube passangers.
I think so!
I also bought a Carver 1600 for under $800, and sold my Classe 400 after hearing more bass, dynamics, openness, and volume from my 86db Mirage m3. They have an adjustable input so you can use a pre that has from only 2 volts to as much as 30 volts or more and match it nicely. The best deal in audio right now that I know of.
I've jumped the eAR ship to swim in the new H2O. This is a startup company that produces the affordable ICE based amp. The H2O has a robust analogue power supply to match the ICE module's analog modulation. It has 150,000 micro farads of power capacitance, and a kilowatt transformer. On the back of it's aluminum black anodized case are Cardas connectors. The H2O is fully balanced. The stereo model of this power house of a class D, is a modest $2k. The mono pair sells for $3k. I ran the stereo model successfully on my 1 ohm speakers.

People are leaving their EVO GENII amps, and, of course, a myriad of conventional amps in favor of the H2O.
