Fun with TDK cassettes.
So I thought I would have some subjective fun with a select range of 1990s TDK cassettes tapes.
Set-up:
* The selection: AD, AD-X, AR-X, SA and SA-X. (no D, no MA*, no SR*, etc)
* Generations were within a couple of years. i.e. I didn't use a 1982 AD-X and a 1992 SA.
* All tapes were calibrated in the same manner, however, input signal was adjusted to the suggested best maximum.
* Noise reduction was turned off.
* A subjective song was chosen. Don't ask me what.
* I played the same segment on each tape until all tapes were eventually reviewed. Yeah, a lot of manual cassette ejections and insertions.
* I used over-the-ear headphones and kept equalization settings constant.
Disclaimer:
I tend to subjectively prefer a wee bit more treble in my sound replications. In other words, musty ol' BASF recordings - that perhaps once sounded good - are out for me. I also expect SA and SA-X to perform well. I need to consciously keep that personal bias under control.
Observations:
* No surprise: The TDK AD sounded the weakest, however, it was still acceptable to be proud to record and give away. If you never heard the others here, the AD sounded good. Note: The AD sounds as good or better than many comparable competitive brands of respective eras.
* A significant improvement was the TDK AD-X. I found the sound step quality was the greatest between the AD and AD-X. The AD-X was warm, clear and present. Noise did not bother me at all. It was a pleasant tape to listen to (but it was still not a SA).
* I found the sound of the TDK AR-X maybe marginally better in terms of clarity and presence over the AD-X. What the AR-X did manage well was a strong input signal - the strongest of the group without noticeable distortion. Bass punch was better than the AD-X. It was hard for me to determine if the noise floor was lower (I know it should be, but my gear may have soaked the difference up). I realize the AR-X is quite coveted, however, if I could not get one I would be satisfied with an AD-X.
* TDK SA - a standard for many did not disappoint. It was crisp and firm. Perhaps in some areas too crisp and maybe even noisier than expected. Overall, it sounded good to me. Refreshing, lighter than "warm". Bass sounded clean and not muddy in any way. To me it sounded more fulfilling than the AR-X.
* TDK SA-X - a legend in many people's mind did not disappoint. Compared to the "crispness" of the SA, the SA-X felt rounded and welcoming. There was lots of room for the sound to expand into, yet everything seemed to remain grounded.
SUMMARY:
In the end, it is the subjective perception of sound reproduction quality that matters. I suppose cost too. Today (in 2026) probably the best balance of value and quality goes to the TDK SA. I also find all generations of TDK SA incredibly durable going right back to 1979. For value, many would say TDK D, but in this lot it is the AD. The best experience made the SA-X win over me. If cost was not an issue, then AR-X and SA-X would be top choices.
