Personal amp evolution

I don't think I can remember them all but I remember my very first acquisitions quite well:
1973 - Pioneer 25-watt receiver.
1976 - Pioneer 50-watt receiver.
1978 - Yamaha M4 and C4 separates.
Law School 1981-84 - went back to Pioneer 25-watt receiver.
1984 - Kyocera receiver to match new Kyocera CD player.
Later in the 80's - Rotel amp and preamp, followed by British Fidelity A-370 amp and MVP preamp, then ARC D-300, followed by Goldmund Mimesis 29 and Ayre V3, finally replaced circa 1999 by my current ARC VT-100 Mk III which is a keeper.

Started w/a Lafayette receiver/ pair of 8"2-ways and a Duel 1209tt w/Empire cart!
Kept TT and replaced w/ Pioneer SX727 and a pair of 10"3-way Fisher speakers.
Still kept the TT and ended up w/a Kenwood KA-7100 and a pair of Rogersound Lab JBL 4311 copies.
Somewhere in here, I added the Original Magnevox CD101 by Philips. I still have this, but needing repair.
I converted the Kenwood to a preamp only, adding a Carver cube to the Magnepan MG-1's I traded up for from the RSLs!
Junking out the TT in favor of CDs, I than gave the Kenwood away and traded up to a NAD1700 tuner preamp to drive the cube and Maggies.
Cube died and was replaced by a Rotel. CD player replaced by an OPPO DV981.
Other stuff thru the years include AT LEAST 4 reel-2-reel of which I still have the Tandberg 3000x,
Maggies swapped for MG 1.6s and a new integrated is on the horizon...maybe the PSAudio GCC250.
What a trip.

Rotel 1080 nice but it kept blowing out a channel
Parasound A21 very nice with a little warmth
Pass Labs XA 160 not quite my cup of tea
Ayre MX-R...hopefully done for now!!!!!

1) Sansui (integrated, can't remember the model designation)
2) Luxman L410 (integrated)
3) Audio Exclusiv P2 (pre) + Luxman M363 (power)
4) The P2, an award collector in the early 80s, was the first used gear I bought; impressively as its musical performance was - especially phono - , it soon showed it had really been used ("worn" rather) and needed to be replaced by: T+A P1200R (pre) + Clearaudio Basic (phono)
5) Thereafter I ventured into surround and replaced the Luxman M363 by T+A A1520 (2 channel power) + T+A DD1510 (decoder + 3 channel power amp)
6) Replaced the T+A 1200P by T+A 1230P (huge change)
7) Replaced the Clearaudio Basic by Quad P24 (tube phono)
8) Dropped surround altogether and replaced everything by Tidal Preos (pre including phono) + Tidal Intra (power)

second system
1) Unison Research Unico SE (hybrid integrated)
2) Unison Research S2K (single ended, class A tube integrated)
