Jazzhound, you're never going to convince ME. I use tapes of material I recorded in my garage apartment in the eighties of myself and several different groups of musicians playing to evaluate my system.
I know the players, the room, the instrument, I was there while it was recorded.
These are played back most realistically and accurately on the tube equipment I have, not the solid state equipment I have and have had.
So talk on, I hear ya but don't believe.
