Your Forever Pieces? What and Why?

All my McIntosh gear are forever pieces.  They have to be as I am now retired and on a very fixed income.

A McIntosh 2105 amplifier. 43 years and counting. I use other amps as well, but the reason I have kept it is NOT sentimental. It sounds really good. That's why they still sell for such obscene prices.

My Klipschorns, bought used by my late father in 1980 and handed down to me in 1998.My KEF Transmission Line speakers which I built in1977.
My Rega 3 TT, which I bought in 1981.My Mullard 10/10 amp, built in 1966, lightly used, still with the original valves that still measure well and sound awesome with both the Klipschorns and the KEFs.

Forgot I acquired a pair of JBL Minigon speakers that my dad purchased in '63.

Need to get them set up somewhere.

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.
