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.

There is no comparison. The newest versions which use the "super tube", are in a different league. Sonically they are much more accurate, much quieter and much faster.

The difference is even bigger in the preamps, when it comes to the REF2 and the REF2 MKII. There was a mid bass bloat which seems to have disappeared as well as a lowered noise floor.

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

Hi Kublakhan,

Does the AR Ref. MK II pre use a single gain stage with no cathode follower like the BAT VK-50SE pre?

Thanks!
