## Description

desertcart.com: RTM C90 | Type One 90 Minute Blank Music Cassettes | Ideal for Audio Recording | Studio Quality | Pack of 3 Cassettes : Electronics

Review: High End Modern Tape! - RTM quality is unmatched in the reel to reel world. It's no wonder that these cassettes are so good. They are a shining star in the malaise of new cassettes...with Type II and IV tapes long gone, the best anyone can hope for is a manufacturer making a good tape. THIS IS THE TAPE. If you have a high end deck and insist on new tape, you won't be disappointed by these. Both this and the 60 minute version are solid. Calibration on a high end deck tells most of the story. It's not a superferric, but it does have a high MOL and a very consistent coating. Background hiss levels are acceptable, especially considering the MOL. HIGHLY RECOMMENDED
Review: For the money, isn't everything? - 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.

### ⭐⭐⭐⭐⭐ Great Tape
*by A***B on March 5, 2026*

Great sounding. Reminds me of BASF type 1. I record without Noise Reduction and bury the source slightly hotter than normal. Works like a charm.
