"D" amps, general discussion who's 1 and why?


There sure seems to be allot of continued "BUZZ" regarding "D" amps. I am reading more and more SET/Tube users and lovers actually recommending and using them.

So what are your thoughts.

Saranwrap of course. Look at his system.

Ribbons can actually act as antennas. He's concerned with insulation (rightfully) yet uses antenna for speaker cables in an strong RFI/EMI environment.

He may make it work, but it will likely be a reactive system, particularly to digital devices, which he has stated that it is.

Anticables work extremely well with the latest Spectron amps, used as monoblocks. I'm biwiring Vandersteen 5a's, using 4 anticables per side. Very quiet background, very musical.
Dcstep, quit chewing on my leg. There is no RFI/EMI environment around my audio gear. The ICE module's radiation is minimized by B&W and the H2O's very heavy barriers do the rest.

If you notice, I am also using 6 ft. of Speltz ICs to reach the amps. They too have the skimpiest of shielding just designed to prevent shorts. My ribbons are only 18" long. Yes, it is Saran Wrap. The plastic touches the metal only barely. It works.

You see, no worries. You are thinking of another class D amp that is famous for polluting.

Reactive system? It is an honest system. Class D amps require rethinking the rules.

When I was running huge Pass Labs monos cabling made no difference.
Muralman1, we're just talking about Class D, RFI/EMI and cables, so why should your leg hurt?

Given your choice of antenna for speaker cables, you're wise to keep them short and away from the digital sources. B&O doesn't do a particularly great job of minimizing RFI/EMI, but your H2O likely makes up for that. Almost certainly your CDP and DAC are leaking RFI, so balanced ICs are wise in almost every system, particularly those with relatively long IC runs, like yours.

"Reactive" because you stated a high sensitivity to insulation on cabling.

I generally agree with everything you say, but don't find your system's sensitivity to cable insulation to be universal to Class D, that's all.

Dcstep, Unlike me ;D, my system is very very sensitive to everything..... especially criticism :D

My Scintillas have 40 feet of gossamer light naked ribbons. And they just do HF. The highs are audibly infinite. In conjunction with my H2O amps, twice improved, I have Henry Ho's Fire preamp too.

I like the NOS Audio Note DAC for it's purity. There is no filter software messing with it.

Tube changes, cable changes, speaker placement, are a devil's playground. I think I just lucked out.
