I STILL use cassettes, have a Kenwood KRC 855 RL headunit, ten disc changer in boot, on underside of parcel shelf, listen to radio 2 mostly and tapes would be Nancy and Lee, Gene Pitney etc, some from early 70's so doing well !!
I even had to get a new CD changer as my old KDC 603 would not play computer recorded ones, so got a KDC C719 MP, as this is the only one that works with old stereo's(kenwoods) on new CD's, CD-R.
Stereo is 12-14 years old repaired twice in that time, both times my fault cost around £200 total in repairs.
