Fellas, dont forget, with Spectral, the RCA & XLR I/Os are wired to the PC board with MIT cable. This is a dream come true for audiophiles. Running MI-350 (personally the best wire I have ever heard ),is a glove match with Spectral. The designer utilized the entire MIT philosophy from input to output. Tampering with different ICs, seems foolish, and defeats the design goals Keith Johnson set out to achieve in the first place. BTW, Spectral pooh poohed balanced lines for years insisting single ended gave better sound.
Detlof, tell me, is that DMA-360 the best SS amp you have ever heard? My guess is that it is...Thanks......Frank
