Strongly agree ! i would especially include the Depth of Image disc, and for the high speed tape freaks, RtR releases. Any of the half track 15 ips tape samplers are excellent .
Best in music to all
'Depth of Image' is one of my go to recordings when I want to do a demo. It is, even to this day, very hard to better and a superb recording. I have a few favorites in the catalog, which has a pretty wide variety as to the type of music, some of which will probably appeal a lot more than others. IME, all of the releases feature superb recording and SQ.
What are your favorites...and what type of music?
