I have not heard as much gear as Bruce of course, but based on my limited experience with Trinnov and Dirac and tube and SS gear this is categorically impossible. Tubes have a distinct sonic signature that cannot be emulated with DSP. In fact, I have always been surprised how somehow even wiht the use of DSP, hardware retains its own character.
Yeah. I have played the Lampi, Linn TT, and Linn Streamer all through a Trinnov in the same system (with Adam Alpha Active speakers), and each hardware retained its own character. In Marty's system, his Goldmund TT and EMM Labs dac sound distinctly different through the TacT
