Join me as I delve into a broken Musical Fidelity Tri-Vista 21 Tube DAC, repair and upgrade it with my own range of improvements.
Follow along as I describe finding and repairing the faults, upgrading and then testing this wonderful Musical Fidelity Tri-Vista 21 Tube DAC. In the end, I was able to achieve just 0.001% THD + noise from this baby, a superb result! I’ll be adding a full written article on the repairs and upgrades to this Tri-Vista 21 DAC soon.
FYI, after an extended listen to both mine and the owner’s upgraded Tri-Vista 21 DACs, this one, with full power supply mods, sounds noticeably better again. Incredible, just need to implement this last suite of improvements in my own Tri-Vista 21 now!
