Well, not really. But the Thiel CS3.7 speakers set-up in the Denver Audio Designs room could be driven either by an all-Bryston system—the new BCD-1 CD player ($2395), BP26 preamp, and a pair 7B-SST monoblocks—or an all-Simaudio Moon system: SuperNova CD player P7 preamp, and W7 power amp. I listened to "Comfortably Numb" from Pink Floyd's The Wall with both set-ups and the differences were both audible and surprising. The Moon system favored David Gilmour's paradigmatic guitar solo; the Bryston the contribution of David Mason's drums and Roger Waters' bass. I could have lived with either.
