I always wondered how good those would perform if you replaced the tape with Maxell UD 180XL-2. That tape was AMAZING. On my Teac reel to reel, after I switched to that, I could no longer hear the difference between source and tape. It went about 5KHZ farther out.
Hi Bob. Reel-to-reel tape has the same with, but is thicker. I never tried it myself but I know some people have. Because of the thicker tape 90 minutes playing time cannot be reached.
