Has anyone experienced fully digital power amps?

I wonder whether anyone has experienced fully digital power amps. Something that takes in digital signals though a serial port and driving the speakers with PCM type signals.

Looked at the reviews and it certainly seems good. There seems to be some chip manufactures working on lower powered stuff, but I like high powered. How to these compare against analog amps of the same price range?

Tact millennium is the best amp i ever heard, by far..

I have compared it directly with the Gryphon Antileon(at twice the price), a Classè amp, Doxa 70s, and the Electrocompaniet amps.
The speakers: B&W Nautilus 801, 802 and several other speakers.

Yes, the other amps sound great, but the millenium is much better in every way. It sounds more natural, more musical, more details, etc....

Regards,
Peter

I read a review that mentioned speaker selection is critical. It mentioned the TACT 2150 being sensitive to speaker loads, especially in the high frequencies. Does anyone know what kind of load it refers to? Most speakers have a rise in impedance like an inductor with frequency unless there are zobels.

Haven't read a Millennium review yet. Since it was developed earlier, it might have similar concerns?

I didn`t notice any problems soundwise with any of the speakers when i tested the millennium...

My friends Thiel (4 ohms) have never sounded better and he used Krell in the past and Levinson before the tact. He traded his ML DAC, Pre and Poweramps for the S2150 integrated, got an upgrade and some change (money I mean)....

They sound unlike tube or Trannies. Black is black, white is white with thundering dynamics yet subtle when required. Good sound stage etc etc. I prefered the Millenium to the Electrocompaniet Nemo mono blocks and to me the S2150 is better yet...

I noticed you mention S2150. How does this differ from M2150? Do you have a turntable in your system?

tubenut · 12th April 2005, 06:38 AM

Perhaps I meant the M2150 as the S2150 is actuallly a slave (power) amp.... His unit is the integrated one with gyro volume control.
I have a TT in my system but the M2150 is not mine..

I use an ECI3 with a Linn Axis / Karma FR TR05 step up and home brew opa2604 Riaa.

I did hear a basic Thorens turntable played through the Tact room correction unit with Tact 2150 power amps the other day.. Sounded very good and still better then the EC Cd player used as digital source. Bizarre, I know..

I had tested TACT millenium for 1 week or so.
Sound seems 3-D and FAR FAR solid like a rock
sound stage is real astonishing.
it was a beast and really FAST

BUT

Not that detailed and a little "cold" ( i dunno how else) to describe it. I prefer my Symphonic Line RG monoblocks, with RG-3+ preamplifier
