Audio Research LS25 Mk II vs Ref 1


Hi Guys;

Has anybody done direct comparisons with the Ref 1 and LS25 Mk II?

Thanks

Well, not the Ref 1, but the Ref 2 mk1 vs. the LS25 mk2.

First, keep in mind the Ref 1 and Ref 2 mk1 use the traditional 6922 tubes whereas the LS 25 mk2 use the newer 6h30 tubes. They do sound completely different. The 25 mk2 is very dynamic and with lots of detail. It sounds similar to a SS piece, with little bloom. Everything sounds very "crisp" with the 25 mk2. The Ref 2 mk1 however has lots of bloom, is dynamic, (although not as much as the 25 mk2) and gives more of a laid back presentation. Don't get me the wrong, the LS25 mk2 is very good, however it all depends on your musical tastes. The Ref 2 mk1 beats the 25 mk2 in bass extension hands down. Probably due to the two massive toroid transformers vs. the smaller transformer used in the 25.

If you are used to SS pre's, then the LS25 mk2 might be a good mixture between tubes/SS. If you are wanting the traditional "tubey" sound of the 6922's, then the Ref 2 mk1 is very hard to beat. (Keep in mind, I have never heard a Ref 1).

Good luck.......
Tony- you HAVE a Ref 1- whats' up? I am surprised to see you inquiring about an LS25! Call me crazy, but I would have thought the comparison you would be looking for is Ref 2 MK II to your Ref 1...
Hi Sutts - Yes I do have a Ref 1, but I have not heard the LS25 Mk II. I think the Ref 2 Mk II may be too rich for my system synergy and tastes and wanted to get a feel for the LS25 Mk II. I still have fond memories of my old SP11 Mk II hybrid. I guess we should include the Ref 2 Mk II in the discussion though. Thanks guys
Owned em all...ref1 was whitish...LS25 was wonderfull...MKII is still good, but 6922's in the pre stage is more musical.
