Teac A-4010S since new in '68 0r '69, Sansui Au-111 since new in '68, Teac A-4010GSL, SX-1980, CT-F1250, SG-9500, RG-2, SR-303, Hpm-150's, Hpm-900's, Hpm-1100's, Pioneer A-5, National RS-255S cassette deck, SR-202, SL-5100 all since new. Have also owned Kenwook TK-140X, Cs-77's and Cs-88's but those moved on to make room for the silver pioneers. I tend to put together and tweak what sounds good to me and then hang onto it for a bit.
