Whose got best class D at this point?

Spiro, There is absolutely no doubt in anyone's mind who have heard my
system concur IC insulation invariably imparts static into the signal. Bare
wire, or wire with just a thin sprayed coating don't. That is my system. The
Cardas was simply unlistenable. The Jena merely faired better.

Well shielded PCs are needed to defeat RFI emitted by the module. This RFI
will enter all other components that are not protected from it.

On the dielectric caused distortion, this may not be evident on some speaker
systems. If the preamp has excellent transparency as a great class D amp, a
very fine driver will pass the noise on. You can bank on it.

Great to see this post really had some legs.Still haven't made choice but seems like PS,Bel canto and from what i read hear Channel Island might be good switch for me.ut if I saty with high sensitivity I think that what I read from 6moons about the Redwine 30 or 70 mono's would be great.For $1500 more the 30 watt than the mono 70's at twice the price.If I get say a B&W Nautilus or other speaker that really needs the grunt they would be out.But again glad to see this thread has gotten soem liage from folks so you all must be interested and putting "Class D into the serch.Along with possibilities like expensive TacT and much more reasonable DEQX it's very "De Jure"

Okay, yes indeed! You are absolutely right. Air is the best insulator, teflon materials are next, but polypropes can be quite nasty. Shielding and insulating are not the same. Shielding is an insulation. I mistook your use of terms. I agree as my system shows what you describe regarding insulation. I find loose teflon to be nicer than the enamels I've tried, even light acrylics. Best regards. This thread has my mouth watering to hear the Red Wine unit.

Its new and just comming out, Nuforce ref 9 V2, here is the info from the Nuforce web site, if its anything like standard ref 9 to ref 9Se now that would be a very good thing. any older amp can be upgraded,


"V2 is a patented technology! Patent application 11/132,810 has been allowed (March, 2007) for issuance into a U.S. patent (will publish patent # as soon as it is available from the US Patent Office). The patent has been assigned to Nuforce, Inc.
V2 board has the same form factor as V1 board to facilitate upgrade of NuForce products."

Most experts agree that the perfection of Class D is a thing of the future (by true "high-end" definition/standards). With that said, I am very satisfied with the performance of the PS Audio GCC-250. It is VERY quit and to my ears is a definite improvement (although very subtle) in performance over my old AR-D240 (which was never an exceptional amp, but certainly not a bad sounding solid state either). With the GCC-250, bass is more controlled and there seems to be a bit less harshness in the highs. Additionally, there is a good bit of power on reserve for demanding musical passages. I like my music loud and I lean toward the classic rock, contemporary blues/jazz side of the spectrum and the GCC-250 does well with this genre. I do appreciate female vocals and acoustic guitar, which the GCC-250 also does a respectable job of reproducing. Bottom line: If you're looking for that true high-end experience stick with class A, class A/B (for now). However, the class D of today is pretty remarkable and there are some great amps available on the current market. While I have not compared many class D amps, I am very satisfied with what PS Audio has come up with in the form of the GCC-250. Note too that the GCC-100 has attained some very positive reviews.
