The Tri-Vista 21 is an extraordinary DAC, upsampling all digital signals to either 96kHz or 192kHz. It features a very impressive class-A 5703 miniature triode tube output stage and superb 13.5kg battleship like construction. Seriously, I’ve never seen or worked on a DAC that’s better built.

The LED lit feet clow red at first, then amber and finally blue to indicate that the unit is fully warmed up and sounding at its best.

Upgrades and New Parts

Where do I start? I’ve installed a matched set of new 5703 output tubes, new socketed op-amps, new premium-grade electrolytic capacitors, new Siemens mil-spec decoupling capacitors, ERO  coupling capacitors, CMC silver RCA connectors and more. Literally dozens and dozens of premium parts from my stock went straight into this DAC, I was doing this for myself after all!



My attention to detail is so insane and painful at times that I didn’t just replace these 5703 tubes, I had to install a matched set, and also remove, clean and reinstall all the little grommets and wires that hold them in place. I
Note that I later removed the LT1028s and replaced them with either 5532 or 4562, all premium parts however.

More Information
