Maxell or TDK?

Another thread where the findings are Maxell and TDK are the best.

Another comment that having the cassette deck bias tweaked for the tape was crucial to best performance ...

Analogique in Manhattan did this for me and the difference was not subtle.

Bias is HF signal above audio band (usually 50-100kHz) used to reduce distortions of the tape. Too much bias on the other hand causes drop in high frequency response. High frequency content in music also plays role of a bias and by controlling total sum at given moment much better extension can be achieved without increasing distortions. Inexpensive tapes can sound like best chrome tapes. I had this long time ago in my Aiwa Deck and it was called HX-PRO. It is "servo" on the bias. Tapes recorded on this deck sounded much better than the same tapes pre-recorded.

Once TDK came out with the SA-X and Maxell with the XL II-S tried those too. Prefered the originals!

All this tape talk as me eyeing another Nak.
