I'm still using many things from the 80's....a pair of Saras ST200 Tower speakers that I got around 1986, Luxman PD-300 turntable with Signet tone arm from about 1988, recently overhauled, so the vacuum system actually works (Just added a new Lyra Kleos MC cartridge to it last December as well).
Also still use a 1998 vintage Cal Audio Labs CL-15 CD player that stills sounds great with my old HDCD discs, bought used, around 2003.
And I even have my old faithful Tandberg TCD3014 cassette deck so I can continue to play my old Grateful Dead bootleg tapes, from oh so many years ago. Ah, the memories.
My amp was until recently, a garage-built tube amp with Russian 813 tubes x 4, Amperex Bugle Boys, etc. Good for maybe 150 wpc class AB, acquired in 2004. Ran the Cal Audio into it directly, without a preamp, for a long time.
Now I have started to upgrade a bit with newer (used, or demo, however) components such as an Audio Research Ref 75 amp with a fresh set of KT 150's and an Audio Research SP20 pre amp. So now I can really enjoy that turn table at last.
We also have a reasonably nice collection of MFSL and Sheffield LP's many of which are older than 10 years, if that counts.
The Luxman PD-300 witth the Lyra Kleos does sound very nice through the ARC Ref 75 and SP20, however it is now really clear that those speakers are in serious need of updating. "Newer" speakers are next up. Starting to really want to seriously improve things now. We will see where all this leads to....
