Anyone here using vintage speakers?

 Mid 70’s Bozak B-401 Rapsodys w egg crate grills..
 Surprisngly good sounding, decent bass.
 Thoren TD-125 II > Schiit Freya+ > Sony TA-N55ES amplifier.
  All original; one owner mint except for one inch by one quarter inch high hard plastic feet that may help the sound by decoupling the speakers from my carpeted wooden floors.
  Every time I fire these up I end up spending at LEAST 2 hours listening to them.

I sold the entire line of Bozak speakers until they closed shop.  The B401 speakers were one of my favorites.  My only complaint was they were a laid back in the treble.  I never did warm up to their aluminum tweeters. 

I have an early pair of Shahinian Obelisk (approx 1980). Obelisk were released in 1977 and are still in production 44 years later. The drivers have changed, but the overall design is the same. I don't know of any other speaker that falls into this long-lived category. They were ahead of their time and sound absolutely amazing. 

In my office system I have KEF Calindas purchased new in 1979. I have Kef Reference 104/2s in my main system. Purchased them about 4 years ago from the original owner in perfect condition. The manufacture date is 1991.

i'm still listening to my ads L470s, which cost me (no kidding) $5 at a garage sale. excellent clarity and surprisingly deep, tight bass for such little boxes. likewise, my polk monitor 10b has outlasted innumerable others  and remains one of the great mancave rock and roll speakers.
