Have been listening for several hours now to this system:
JRiver MC on Win7 laptop -> ASIO USB -> Bel Canto RefLink -> Violectric V800 -> Bottlehead Crack (CBS-Hytron 12AU7 and Sino 6N13PJ) -> T90
The extremely low jitter S/PDIF from the RefLink to the ultra-low noise floor V800 combined with the rest is resulting in an auditory delight. What little digital glare I experienced before is gone. The euphonic effect contributed by the Crack+tubes is resulting in the best sound yet experienced with the T90. This is one spectacular experience. So I guess it is fair to say that the Crack+T90 scale well with source quality. Later will roll in the RCA cleartop 12AU7 and GEC A1834.
