Hello! Here's my two cent's worth. I have owned many if not most of the gear listed in this thread. I have an AUDIOMAT ARPÈGE with Sonus Faber Grand Piano Home speakers. Please.....no Musical Fidelity with any Sonus speaker, it's a definite mismatch of the worst kind. Bright and thin sounding. The Arpège is probably the best kept secret in all of high end audio. And a better value than the more expensive Prelude and Solfège from the same manufacturer. On the Solfège, I never could go for the '' 6550'' tube sound anyway, preferring the harmonic sweetness of the EL 34 tube that the Arpège offers. By the way VERY reliable also with loads of class.
