Personal amp evolution

I got a superscope cassette player with built in speaker, I believe it was the C-101A. It was a Christmas present in 1975.
My next upgrade was a Centrex "by Pioneer" compact am/fm, cassette, turntable complete with a four wpc amplifier.
My first real receiver was a Kenwood KR 2400- 15 wpc model, foll0wed by a KR 4070 40 wpc in high school.
My high school graduation present was a Luxman 1050 55 wpc receiver and at that point I knew I had something special.
In college I bought a used McIntosh 2205 amp that I owned until I bought a just released Mark Levinson 23.
After several years with that, I quickly went through a Rowland Concentra, Sonic Frontiers Power One, Pass Aleph 3, and X250 amp.
I have now settled down-I think forever- with an Air Tight ATM with all NOS tubes.

1972 Sansui can't remember the model.

1985 Yamaha A1020.

1990 Yamaha B2-X.

2003 Adcom GFA 565 Monoblocks.

Just a quick update:

1988 Pioneer A-656 MKII (ALR Nummer 3 stand speakers)
1993 Harman Kardon HK1400 (ALR Nummer 3 stand speakers)
1998 Rega Mira (Original) (Mission 751 monitor speakers)
2003 Linn Classic (Mission 751 monitor speakers)
2004 Linn Wakonda/LK85 (Mission 751 monitor speakers)
? some tube integrated ? - (Mission 751 monitor speakers)

So far it's been all solid-state. If I can find a good tube amp to drive my 751 speakers I might switch someday....

2004 ... just found one: Jolida JD302B: even right out of the box beats all of the above hands down, I think I just got converted...

Good time for me to add my list as I just made a very satisfactory upgrade :

1982 JVC receiver - 60W (ha!) plus cheesy tone controls

1991 Nakamichi receiver 3 - 35W - blew the JVC away

2001 Rotel RA-972 integrated amp - 60W - really blew the Nak away

2004 Acurus A200 amp - 200W - harsh and brittle using RA-972 as preamp

2004 Rotel RC-995 preamp - really sings with the Acurus amp

I should be happy for a long time to come as the RC995/A200 combo sounds better than I could have imagined and has more power than I will ever need (never say that huh?!).

A UK perspective:
1978 Quad 45/303, lasted 20 years a very good early SS comb
1999. E.C.Audio Finestra (early Tom Evans)/ Quad 606, a clear improvement, particularly the pre. Now used by my son
2003. Finestra/ Pass Labs Aleph 3, I can'nt see myself getting rid of the Aleph
2003. Graaf WFB-one/Aleph 3, very good Italian valve pre with good phono stage.
2004. Conrad Johnson Premier 17/ Audio Synthesis Passion Phono stage/Aleph 3. As near perfect as I can see myself needing ( I know, we all say that)
