I'm interested in sometime buying a (used) MF Tri-Vista 21 upsampling DAC ( I believe to 24/192). My questions for anyone out there are:
What is a reasonable price range to expect to pay? Anywhere in the US that provides service and/or upgrade mods? In the event that I need to replace the tubes, where can I find a reputable dealer/supply for that? etc.
Thanks for any help!
