Audio research LS25 any opinions


I have been thinking of buying an LS25 and than eventually upgrading it to the mkII version. Can anyone give me some feedback on newew AR pre amps.

Dem or anyone else, Did you ever compare the vt100 mark II using a great solid state preamp verses a tube preamp ? I have the pass labs aleph P which is as quiet as a passive preamp. For my phono stage I have an ARC ph3. I notice I get a wonderful tube clarity when I use the ph3. I wonder what my vt100m2 would sound like with an LS25 or ref1 in place of the pass labs.
Knowing that interpretation of sound quality is a personal thing, I'll give my 2 cents here. I owned an LS 25, considered a mark II upgrade, but then a/b compared a MArk II, against the Ref 2 and a VAC renaisance. While the Ref 2 has sonic virtues over the LS 25, even with upgraded NOS tubes, the VAC literally outpeperformed the REF 2 in all categories. I have been a long time ARC fan (still am!), but there are formidible competitors with outstanding products!
i have audio research ls-15 and iam using a classe amp right now. I am thinking of changing to the vt-100tube amp would this be a good move?
I have just had my ls25 upgraded to the mk11 version, I was using nos tubes that made an incredible difference, I have not had the chance to evaluate them side by side but so far it looks like it's going to be a tight race. I would compare the two before doing the upgrade and keep in mind you are limiting yourselves to just stock 6h30's since I don't believe anyone else makes them, I did not think about the tube limitations before I had the upgrade done. just my opinion.
Gjc: What brand NOS tubes were you using with your LS25? What were the improvements over the ARC 6922's? Thanks
