BTW, I agree with you on the TD-125, which is still one of my favorite TTs-a true classic (or vintage, or antique (pick your favorite adjective).
I still have some cassettes made with a TD-125 MK II, ADC XLM III and a TEAC A-860. The quality of those tapes, which would have been made in the late 70's, in particular the bass (I always recorded with headphones, so no room effects on the TT) never a particular strong suit of cassette, is outstanding. Unfortunately, that table, and that deck (which beat any Nak I've ever used, for sound quality), are long gone.
Back before the iPod and CD-R era, I always used cassette for vehicles, because I felt a car is no place for CDs, unless you want to destroy them. I still have a Soundstream player (from back when they were made in California) in the beater truck. I can instantly tell when I pop an old tape made on that combo in the machine; even though they are Dolby B, they sound better than the Dolby C tapes I made later on a Rega 2/Nak CR2A combo.
