Audio Research comparison

I'd still like to get an un-biased comparison of the old Audio Research Power Amps: VT100 MkII, VT200, REF300 and the newer solid state input versions. I have heard opinions, but they have all been self serving. So I'd like to hear from someone who has really compared the two designs. Also I'm interested in the comparison of the new pre-amp designs with the older ones LS-25 Ref2 with the MkIIs.

i recently went with a couple guys from this site and did an a/b with the LS25, LS25mkII and the ref2mkII.

the ref2mkII is in a whole different universe. Amazing.

No one liked the LS25mkI. Very thin, weak bass...the LS25mkII was a SUPER improvement, more involving, better bass, the music just had more mass with a deeper soundstage and all were impressed. i came close to love but i only had eyes for the ref2mkII after she showed her stuff.

if you do a search of arc 24 bat 50 you'll find the thread.

hope that helps

the only arc preamp that was made without a cathode follower was the SP12 from the 80s.

in the demo we did out here 4 of the 6 of us preferred the arc ref2mkII to the BAT50se but we were listening on a pair of arc300s. apparently there's synergy when using the bat pre with the bat amp so maybe the comparison wasn't a fair one. they're both amazing preamps however and if you're offering, i'll accept either. :)

gmorris, was your friend using nos tubes on his ls25? anyway, of course it's all subjective and component dependent - this is what we all stew about in our sleep/lack of.
anyway we listened to the ls25mkI through a pair of arc300s. perhaps this brought out something unusual in the LS25. and changing the tubes should of course make a difference. as far as the vt100mkII vs mkIII i've heard many people say they prefer the mkII. i have the mkII but haven't yet heard the mkIII so i can't comment.
