Thanks to Steve & Andy. I've been listening to the KGSSHV Carbon with the Golden Reference psu for the last three or four days now. Here's my take on the Carbon against the BHSE and DIY T2 which was in response to Muveling's take on the trio on headfi:
You memory is nearly spot on Mike. I commend you! I personally will rate the T2 as the best amp among the T2, KGSSHV Carbon, and BHSE. The BHSE and KGSSHV Carbon are equally excellent in my book with the Carbon having considerably grander musical presentation with noticeably wider and slightly deeper soundstage than the BHSE. Spatial imaging are about on par but the wider soundstage does allow the Carbon to produce a more enveloping musical experience. Musical details just floats from the background with better layering compared to the BHSE. On the other hand, the BHSE does offer a more intimate presentation with smoother and more liquid tones from top to bottom especially in the midrange region. Bass doesn't quite hit as hard and authoritative as the Carbon but nonetheless is still very much satisfying to my ears. The SR009 out of the Carbon is actually quite a bass monster surpassing the Hifiman HE1000+Susy Dynahi setup on both texture & details and matching its output. The DIY T2 loose out to the Carbon very slightly on the width of soundstage but does make up in the depth department. It is able to render sweeter musical presentation (yes, even more than the BHSE) and about on par at resolving musical details. Bass output is slightly less than that of the Carbon but the T2's bass has more bloom while the Carbon's bass is tighter and come at you at greater speed. This is my take on three amps with the SR-009 so your mileage may vary.
Anyway, I now have the KGSSHV carbon for several days now. Mike and I are quite blessed to have the same builder who executed the build to perfection. Both of our units come with the "Golden Reference " power supply. My unit uses a custom build Khozmos 48 steps attenuator while he goes with the Goldpoint stepped attenuator with exotic resistors. So far my amp has been nothing but pure audio bliss to listen to. It runs cooler to the touch compared to the T2 but definitely warmer than my 500V KGSSHV. Listening to Carbon really make me appreciate how much KG, Birgir and the team continue to push the design envelope. I sure wish the Carbon was there at Tyll's Big Sound Event. I don't see how the HE1000 and HD800 can even come close to the SR009 if the BHSE and KGSSHV Carbon were there at the event. IMO, of course.
