Audio Research LS2B mk2 cap ugrade

Replace the caps on the power supply bypass, I could yes. Trying to get ideas of what to do with this thread and articles that are on the net. There are caps on the board listed as 625 and the equivelent with V Caps are rated @ 600v, I dunno if that will be an issue, I have no knowledge of electronis except what I can edjucate myslef with. Upgrading with sheilding and other stuff may not be anymore than a tweak, I have talked to a company does upgrade work and that is some of the upgrade work they can do. I am lookin for the best impact, I'm thinking it will be in the caps. But I don't wanna go overboard too much with stuff like sheilding and this and that when I can put that money towards a ARD Ref 1 when the funds come into great supply, I had a chance to get a Ref 1 a few years back for $3200 and I am still kicking myself for not doing it. But when I say get a Ref 1 the LS2B can be run on the SE part of the amp, I always use 2 preamps, with it, SE and BAL.

The input, I think if it follows suit with the rest of Classe amps because Classe does not list the manual and without sending a email to Classe, the 100-101 and 200-201 are 75 kohms while the 300-301 and 400-401 are 16 kohms.

I have also used AR LS9 with it with a Krell Showcase DVD, that was a nice combo but I did not like the stepped volume on the LS9 as it did not have enough steps.
