Help me cull my amps

[guitarjunkie]

This is my stable, I'm looking to get from five amps to two; OK, three.
My approach- CD (very consumer-level) and vinyl sources, also some home studio work (Tascam 564, AT4040x2); don't get much above 95 db most of the time I would guess. JBL L200T3 and Braun 710A are main listeners; also rebuilt ADS L750/II into L690 towers.
1) Marantz 1200B. Needs service and who cares. Low power OK, high power is distorted. These are supposed to be great. Very Likely a keeper.
2) Phase Linear DRS900. The polarizing piece. Hums, 120 Hz?, 180 Hz? Obviously needs service. Many cautionary and dismissive statements here; not the "real" Phase Linear, blah blah blah. I'd like to keep, it's pretty, but worried about hardiness of the piece and potential for damage of speakers, for instance. Ideas?
3) Onkyo Integra A8017. My go-to amp. Love it, tough to imagine anything better, but I'm sure some would say there is a lot to learn on this point.
4) JVC A-G90. Solid amp. One output 3db down due I think to using with a speaker with intermittent wiring, causing amp damage? Great except for no stereo reversal option.
5) Proton 520. OK, doesn't seem as clear as the A8017 or the JVC.
Prolly has to go.
AND... Phase Linear P3800 (well-regarded preamp) that I could use with pro amps (QSC, Crown, Yamaha, whoever's around these days) or the DRS900.
Make me smart....

Only one i know i'd lose for sure is the Proton, if only they sounded half as good as they look.

The Marantz should be gone over by one of the experts out there, i'd imagine it's on par with the best integrated's of that era.

The JVC might be a gamble as it could cost as much to fix as it's worth.

Onkyo Integra is generally good stuff, i'd be happy to have a plug n play integrated of that caliber around for stand-by duty.

I know little of the Blaze Linear, but it seems like a sensible layout and robust build with discrete components. Logic would suggest that workarounds exist for any known issues, and it wouldn't surprise me if there's a competent tech out there that specializes in making them all they can be. I'd hold out long and firm on that one as i think it has the most potential of the units mentioned. I'd put some effort into learning more about this amp and what's possible with it.
