Recently found some possibly NOS pc2002m's one of which I bought. Displaced an M-85 wired to 4 infinitesimal 0.2's in my main system. In parallel amp. see's 2 ohm load, not an issue as their volume is slight, just an accent to fill in walk around dead areas. My question anyone do any critical listening between these vintage amp's ?

Can't comment on a M-85, but the PC2002M is excellent. Just be sure to remove the corrosive "sony" glue.

Please post here at least one time a week, and stick around here More often!

Beautiful System you have there!
 
Update, Was first to call on add, waited to see amp...should've just bought both. Looks aside I went inside...doubt its been plugged in !!
Buying vintage Infinity for 25+, added Yamaha for 12+ if it's not perfect I sell when I find perfect. That said..what I've now I'm keeping, and the market seems to be drying up.
Working on the dedicated entertainment / T.V. room, Yamaha CX-1000, M-85 wired to Infinity RS111b's, M-65 to Keppa 7's. Odd pairing but it's a good size odd room...
Cheers
 
Back to the sound difference ? In that set up I turned all off leaving only 4 infinity infinitesimal 0.2's wired in parallel to either amp.
both amp's are 9's and tested excellent spec. With controls set then back and forth as timely as possible, I found a slight edge in detail to the PC2002m and the edge in bass to the M-85.
The little infinity's test well as they show nice detail with little muddy bass (enter the sub woofer). Could be me trying to justify the urge to buy more stuff .......
Any opinions out there ?

It's not my intention to doubt your claim, but maybe you could give us some examples of how you felt the M-85 outperformed the PC2002m?

Sorry for my delay, mayby I should have included the M-85 seems to be the perfect match for the NS-1000M's, I have played with the Yamaha PS-2200, M-2, M-70, PC-2002 and many non Yamaha amps. It seems to me the M-85 is the cleanest amp with enough power to drive the 1000s in a class A mode I have tried. JMO!

I am running 2 pairs of NS-1000m inverted stacked, being driven by 2 M-85 amps (One amp driving left stack other to drive the right.to minimize crosstalk). Sitting on top of 2 NSW-215 subs.
 
I use a M-85 to power watt hungry speakers such as my Pioneer HPM-200's and Infinity QLS1, without breaking a sweat.
That said I wouldn't mind trying a PC2002.

The PC2002 was a work horse of the mid range sound re-enforcement industry for a long time. You might find one from a local AV rental house. Worth a look.

If the thread is still relevant, then I don't think it really matters. The new forum upgrades included the "Similar threads" listing at the bottom that wasn't there before. I'm 99% sure that is what is causing so many old threads to get bumped back up. It's kind of interesting to see some threads in there that are over 20 years old. Not sure if maybe there is a way to adjust the date criteria of the threads that appear there...

When the OP has not been on ak for at least 10 years and respondents have been silent for 2 years. Other than that it is a current thread.

I mean we are discussing zombie equipment with numerous zombie components.

Like the thread in Marantz with Tony asking about 'new' information since all he has read is 5-10 years old....on a 1974 Marantz 2240 and a group of speakers from the same time period, maybe as late as 1980 or so, everything 40 years old and 5-year old information might be dated? really?
