*by M***N on 15 April 2025*

Good to great....very nice type one tape. Would and will buy again. No problems with playing, good solid feel.. I haven't taped since he earIy1980s. Then used the best non metal TDK and Maxell had. I did do a careful listening on my refurbished Teac deck. Used Steely Dan song aja original CD. Sounds grrrrreeeeaaat! Compared this tape with Maxell type two? XII-S and Maxell type one UR. The Maxell type two was a clear winner. I used the correct Bias, I hope. The RTM C 90 wasn't disappointing and will cont. to use as long as tape shortages last. The Maxell UR was a bit better at mid range. The RTM handled the highs and lows very well. Actually was surprised at the tapes I tried in contrast to what I've been hearing. I really appreciate a good Type one tape as the RTMs. I will not pay the steep prices for a quality metal tape..now off to TDK land for a test.
