Spectron Musician III MK.2 or Audio Research DS450

If D-sonic is price competitive with wyred with alternate/newer technology I will have to read up on them. Last time I looked, they were selling essentially stock Icepower models in a box for reasonable cost. That's not hard to do, and might offer good bang for buck for many. Wyred, Bel Canto and others cost more but added enhancements like custom input (for better results with a tube pre-amp) and power boards for better power supply.

Jult52..Dennis brought up the zero feedback issue in my conversation with him last Sunday and pointed out this the
is the problem with other Class-D amps. Other companies have zero feedback amps including Hegel, Sanders Magtech and Soulution just to name a few.

Mapman..Dennis at D-Sonic pointed out that he only uses B&O
ICE amps for the surround channels only in his multi channel home theater amps. He has done major mods on the SOA core amp. On The D-Sonic website select the products tab and click on the 6Moons picture which takes you to the review. Go in several pages and there is some good interior photos of the SOA amp. You will notice a red p.c.
board on a raised platform which is a modified input stage
that Dennis designed. He also added EMI/RFI shields and filters and added a higher quality A.C. filter which improves grounding, and uses all silver teflon wire.

Ahah, another delicious thread on one of my favorite types of amps... I see I have missed some intriguing technical development in the last little while. G.

Audiozen, I don't mean this to be a antagonistic question.

I'm interested in which switching amplifiers you have had first hand experience with in your system and what speakers you are using?
