A moderate priced dac


I borrowed a musical fidelity tri vista 21 dac from a friend and I was very impressed with the sound compared to my parasound p5 pre. This dac is over 10 years old. Has the technology changed enough that a moderately price dac can compete?Any suggestions?

I’ve been looking at a GUSTARD DAC-X20 Pro.
Any one have experience with it
Goes for about $800 new, $4-$500 used.

tubed dacs are excellent. You are in for a real treat. And the statement no less 😊
@mountainsong I even found the perfect wave dac mk2 to outperform psa's directstream. Tried to upgrade to the dsd twice over there past five years and ended up reselling the dsd both times.

@audiomaze if your question is directed at me, I was speaking of the tri vista dac.  The v90 is a $300 dac that I would probably not attempt to work on.  Parts cost would probably be more that the dac cost!

In general there are a few standard options to upgrading any component.  Power supply capacitors, signal path capacitors, resistors in key areas and AC filter choke.  After that convert to point-to-point wiring, etc.
