Personal amp evolution

Seeing the over night success of the speaker evolution thread, it may be interesting to see what type of amp(s) we have all run. Same deal as the other thread-we will sort of create a puzzle of our systems you'll have to visit multiple threads to put everything together!!! ;)
For me I started:
Adcom GFA-565 monoblocks
Rotel RB-990bx
Jeff Rowland Design Group Model 5
Balanced Audio Technology(BAT) VK-60

either a CAT JL2, BAT VK-75se or Tenor 75Wp on the horizon.
Over the past 25 or so years, I have had
several systems, the power amps from first
to now were:

Kenwood Integrated (model?)
SAE 2100
Marantz PM80
Parasound HCA1000(still have)
Forte Model 5 (borrowed amp from pal, buying
one for myself).

The speakers have all been dynamic two way
mini monitors.

Anybody have opinions on comparative sound
quality between the last two amps? I'm still
trying to decide...
I started in 1975 with a Sears Roebuck receiver. In 1977 I purchased a Japanese solid state integrated amp. In 1990 I purchased a B&K ST-140 solid state amp, used various pre-amps with it. In 1993 I bought a Nobis Proteus Pre-amp and Signature 45 wpc tube amp. In 2002 I bought a Magnum Dynalab MD-308 solid state integrated amp which I just sold. In 2007 I bought a JoLida JD1000RC 100wpc tube amp. I have been searching for a long time, for that "liquid midrange". My speaker evolution is even worse in this search.
Lloyds receiver
Kenwood receiver
Marantz 1090
Added Marantz 170DC power amp,used pre-out on 1090.
Aragon 8008BB
Mark Levinson 335
2-Mark Levinson 436's
How does owning a McIntosh MA6500 Integrated Amplifier sound to you?

McIntosh MA6500 Integrated Amplifier - Get the MA6500 Integrated Amplifier Catalog by McIntosh Laboratory, Inc.
-Harman Kardon Citation 24 (from 1988 and it still works)
-Adcom GFA 555 II (great for loud music/party system, bad with thiels and critical listening)
-Muse Model 100 (one of my favorites from long ago)
-NAD 314 (still have it, and love it in my son's room)
-Dynaco ST 70 (sweet sounding little amp)
-Bell Stereophonic Tube Integrated (totally retro tubes out the yin yang) from 50's.
-Parasound HCA 800 MK II (didn't do anything for me)
-NAD C272 (amazingly clean puncy amp for 450 bucks used)
-McCormack DNA 0.5 (sweet midrange, great bass,not very refined treble though)

-McCormack DNA 225 (very nice powerful fairly transparent amp, one of the great values out there)

-McCormack DNA 0.5 Deluxe / Smc Rev B (lasted about 2 weeks..excessively bright and annoying, seemed to emphasize sibilance)

-Aragon 8002 (stock and then modified, very good very inexpensive amp, punchy bass, open mids, recessed highs,not as good as stock dna 225 on mids/treble but equal in bass drive, to a point of course)

-Audio Research 100.2 (this could be the end of the line for me. Most musical amp i've ever had by a long shot)
