Summary:
I'm absolutely thrilled with this preamp. I used to have a Audio Research Reference 2 mk2 which I compared to LS5 mk3 and I liked LS5 mk3 better, so I started to search for a used LS5 mk2 or mk3, Reference One and LS25 mk1 which all uses the 6922 tube. ARC's hybrid designs with 6H30 are not my favourites of ARC preamps.
I found a buyer of my Ref2 mk2 and needed a preamp until I found what I was looking for, and found a used LS12.
Finally I also found a Reference One which I still own.
To my ears this is the best Audio Research preamp I have heard so far.
Better and longer decay of notes than both Reference amps. A better and more well defined soundstage. Better microdetailing which give a more lifelike vibrant sound. The only region where the Reference preamps are better are in the deepest bass, where they reach a little bit deeper, but still they don't have the resolution in the bass that LS12 have.
This is a absolutely fantastic little preamp that should be back on ARC's program.
So my Reference One will be for sale soon.

Strengths:
Perfect soundstage. Natural and very lifelike timbre and decay of tones.
Absolutely transparent with no character of it's own. Very quiet, fast and dynamic.

Weaknesses:
None so far

Summary:
This replaces my longtime favorite, a Bryston BP-25. I have been a die hard Bryston fan, but I can't get over the world of improvement in this LS 12 over the Bryston! Smooooth sound, phenomenal detail and dynamics the Bryston just hinted at! Want punch? Try the LS 12! You might have to scramble as A/R is phasing this preamp out, but if you hurry you can get closeout pricing from Audio Video Logic. I've never heard soundstaging like this from any other manufacturer. It sounds like tubes, without tubes! Beautiful build quality too. I was a little nervous to give up Brystons warrantee peace of mind, but you know it's about music, and I'm floored by the sound of the LS 12! Judging on A/R's past preamps, I shouldn't have any problems. This is a gigantic value, and at the closeout price a steal!! If you can't find an LS 12 and need something economical, try the new SP-16. It's a tube pre, and supposedly better than the 12. INCREDIBLY RECOMMENDED!!!! This company really is "The one reference!!"

Strengths:
Soundstage separation, inner detail of inst. and voice timbres, tube sound through solid state. INCREDIBLE!!!

Weaknesses:
Not enough inputs, only bal. input for CD player. A warrantee VERY limited...3 years to first owner only. (I was spoiled by Bryston's commitment to its customers.

Summary:
I finally found a preamp that, in my opinion, works well with my system. Now that they lower the price of this unit,(List: $2495 now at $1500), I think it will be very difficult to get a "new" one in the market today. The sound of my speakers using this pre-amp was very articulate. Vocals and other freqs. were so defined compared to the old pre-amp that I have. My background is in Electronics and Communications engineering. I had experienced in acoustics too. If you are shopping for a new preamp, check this model. You will not regret it.

Strengths:
Very nice presentations in terms of musicality. Fairly price. Aesthetics is top rate for simplicity. Made by a manufacturer (Audio Research) that can be trusted.

Weaknesses:
None
