How do Digital Amps Mfrs. compare in sound?


I am so excited about all the reviews of various digital amps out there. I just know this is the future of audio because the value is just too irresistable.

But, there are so many companies out there: PS Audio, Bel Canto, NeForce, Wyred, Spectron, etc just to name a few. To compound the issue(s), the modding companies like Cullen Circuits are upgrading and modifying digital amps. So are there differences between these companies products' sound or does digital equipment sound homogenous? Where does the biggest "bang-for-the-buck" lie when it comes to digital amps? Has anyone directly compared any of these digital amps to each other?

I've had the Continuum 500 for about nine months now and would have no reservations recommending to any music lover, driving almost any speaker.

Stanwal said this and much, much more:
""Not a single master of analogue power amplifier engineering has turned to Class D. Shouldn't one know this, and, ask 'Why?’
By their nature, electronic engineers are usually eager to "migrate into the future technology"."

You spout these things as if you have some special knowledge, or, perhaps, thinking that if you say them with a deep enough voice and authoritative enough delivery then people will believe you. Actually you weaken your overall arguement with such drivel. Kijanki mentioned Rowland and there are others.

If anything, my guess is that a very large proportion of designers stick with what they know and avoid migration into future technology. Othewise, how can you explain the overflow of SET tube amps on the market today? That's only my assumption, but I think that resistance to change is highly prevelant, including among posters here at A'gon.

Magfan said"

"All amps run off rectified AC with the exception of stuff like the Emitter and some preamps, which are powered by banks of batteries. The purity of pure battery power is tough to argue with."

Actually, the Power Factor Correction module converts AC to DC in the 312, Continuum 500 and most other current prodcution units that are used in connection with the outboard PC1 PFC module.

When I asked Jeff Rowland if the conversion to DC provided the Continuum 500 with the same benefits as battery power (removal of AC noise) he said, "exactly." Beyond that, all I know is the Continuum 500 is, by far, the best integrated amp I've heard for powering dynamic speakers like my Vienna Acoustics.

I think that people are confusing swithcing with digital. There's nothing digital about a Class D amp.
