## Description

desertcart.com: RTM C90 | Type One 90 Minute Blank Music Cassette | Ideal for Audio Recording | Studio Quality | Single Cassette : 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

### ⭐⭐⭐⭐⭐ High End Modern Tape!
*by A***R on December 11, 2025*

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.

### ⭐⭐⭐⭐⭐ Quality blank tape
*by M***N on August 25, 2026*

Don’t think it could be much better!

### ⭐⭐⭐⭐ Better than Maxell in quality, but more expensive too.
*by C***S on July 9, 2026*

So, this was the first tape I got in the mail as my wife had ordered Maxell cassette tapes, but they were going to be delayed. I brought this as it would arrive before the tapes, and I wanted to make my first mixtape sooner, rather than later. My first mixtape came out amazing, no drop in quality and hardly any grainy sounds from the playback. When the Maxell tapes came and the playback quality testing was done with them, well, the results were not what I expected or was looking for. I compared it with the first tape I made that used the RTM C90 and the difference in quality is night and freaking day. RTM C90 tapes are vastly better than the Maxell in my experience. That said, it brings another point of contention some might have when looking for making mixtapes. Cost wise, it is hard to justify buying a pack of 3 for the price of $30. Buying one tape for $10 while not bad for the short term, isn't really great if you're looking to make multiple. In terms of quality, I would recommend these over the Maxell without a doubt, price wise well...it depends on how often you'll be making mixtapes. So keep that in mind.
