Wonderfully Euphonic Component Nominations

I have a pair of Diatone based loudspeakers I got from Japan, with enclosures from Wood B. Lansing. The Diatone is a 6 1/2 inch driver no longer made, and it sounds so musical that critical listening takes a back seat to enjoying the music.

I own a M. T. DAC and the tube output needs repair. Any suggestions? Please don't suggest I buy something else!
Thanks.

Creeper, I don't think I'm being defensive but my response was on the topic of this thread from a different angle. I have his historically listened to vandy's, non-upsampling tube DACS and highly regarded tube pre-amps, the last one was the Hovland, and found these different pieces just O.K. It's just personnal taste in the long run but I'm not looking for a "fat" overly warm sound in my system. The reference of live music has many colors/timbres not just one overall euphonic coloration. It has oftened been stated to try not to use wires in a system as "tone controls" because you can compound a present difficulty, I believe the same thing can happen when a listener uses a euphonic piece upstream in their system to get rid of harshness, glare, or an etched quality.

Most older Conrad-Johnson tube gear falls into this category. I have experience with the CAV-50 and EV-1, and found both to be pleasantly "big-hipped".

Sonus Faber speakers. To my ears, they posess a liquidity and warmth that make music a little more sweet than reality. But, who cares?!
