The longest you have owned any gear?

My Ariston RD11S TT. Bought new in 1977 for $280 w/o arm. Added an SME 3009 and a MicroAcoustics 2002 cartridge. Presently have a Grace 707 and Denon 103 on it, along with a Hiraoka SE-22 mat (bought new in '78 for $20 from Harvey Sound, NYC). The Ariston/SME was purchased from Audiocom in Old Greenwich, CT (best HiFi store in Fairfield County).

My listening room :-)

That would be my Pioneer Elite PD-65 CDP. I bought it around 1992-93. With all the reasonably priced DAC's available today, it now does duty as a transport. The thing is a tank.

I was a high end dealer back in the early 80s and sold Phiiips CD players. Kept a CD-80 for myself and had it modified by someone in Iowa, I think. I also was a dealer for "Speaker Art" by Bob Gross. I have a pair of his Odessy speakers. I have spent the last 20 years trying to find a CD player that is as good as the Phillips. I've tried it with external DACs but the one in it sounds better than anything I can afford. My latest effort to replace it is with an Oppo 105. The Oppo sounds good but is not as musical or detailed as the CD 80. I'm 78 years old so my hearing may not be up to the task but I have some good hearing aids and still enjoy my music. One unusual thing. I just purchased a Naim Supernait 3 amp and the remote for it will control the CD player. 
Would like to hear form anyone who has "Speaker Art" Speakers or a Phillips/Marantz CD 80. Terry

My Thorens TD-166 MKII turntable that I bought new in 1977 while in high school.  I had it refurbished in 2019.  I use it almost daily.
