Your Forever Pieces? What and Why?

Matching pair of Harman Kardon Citation II tube power amps completely restored with the best components (1961). Matching pair of Dynaco PAS-4 tube pre-amps (Panor version) completely restored (1995), Pioneer PL 50 turntable w/AT 8008 reference cartridge (`1975), Matching pair (quad) of Meadowlark Kestral coherent transmission line speakers (early 2000’s), pair of Martin Logan SL3 Electrostatic speakers (1996).  Some of this is very old, but I’m older. 

Spendor SP 1/2’s...will be buried with them! Simply the best.

My oldest factory piece, still in use(since 1980): a Magnepan Unitrac I, tonearm. The only change made to that, was creating an adapter, to allow upgrading it’s interconnect cable. Now mated with a Soundsmith cartridge, a golden(maybe platinum) combo. Also, circa 1980, one of my customers requested an actively crossed over pair of 10" driver, folded, 8’ transmission line woofers, to mate with his Acoustat Model IIIs. After building his and hearing the results(with a modded Hafler DH-500, driving them), I built a pair for myself. They’ve been providing fast, dynamic/impactful, tuneful bottom end for me, ever since. A few years back, I swapped out their Milos Nestorovic sourced, 10" drivers, for Seas L26RO4Ys.

Mirage M1si Speakers.  Mirage M3si speakers.  Because they sound amazing.
