Whose got best class D at this point?

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.

I have just switched my Mardis modded Trend amp to battery power and to my ears, this is the best thing I have heard in a while. I just went down to Advance and bought one of those rechargable jumper battery packs for 59 bucks and plugged the amp into it. The difference in sound-staging and impact as well as noise floor reduction is amazing. I have always been a tube guy but this is the best solid state I have ever heard. I have previously owned the nuforce 9, ps audio trio, and the sonic t amp and this far exceeds those IMHO. You just have to try this to believe it...a total investment of 325 dollars for amp and battery. My ic's and speaker cable cost more. Has anybody else tried this yet?

Sanders ESL amplifier. Not class D but unique voltage amplifier. My D*200s packed up after 1 year, very disappointed! decided to give the Sanders a try while the D*200s were being repaired. Don't get me wrong, the D*200s were wonderful amps, but the Sanders is quite a step up the ladder - superb ability to handle transients, very powerful, dynamic and HF and midrange is one of the best I've heard from a SS amp. I have no affiliation with Sanders but want to share my experience with this new amplifier!
