ARC LS1, LS2, LS3 , or LS7, which to buy?


Oh great and knowing Audio Research mavens, I have around $750.00 to spend on an ARC preamp. The models listed above are all in my price range. Can anyone sort out the sonic characteristics a bit for me, I have no way of auditioning any of these. Balanced outputs are not required. This is the start of a new system, so info on solid state power amps that have a synergy with the ARC preamps would be appreciated as well. Thanks, Marty.

I had a LS2B and my LS5B MKIII was much better in every way. Now it has been modded by GNSC and is even better.

Suggestion: I may be crazy, but am a convert to Walker Extreme SST on the tube pins, XLRS and PCs.

Marty, John is absolutely correct about the balanced design of the LS2B being half baked. The device has XLR and RCA outputs, but only RCA inputs. The XLR outputs are using some kind of technical alamagoosa to fake the balanced signal. . . . and regardless whether its sound were 'pleasing' or not, it does lack the phonostage you are seeking.
I have replaced my LS2B January last with an ARC Ref 3.
I have had only experience with the 4004 Mk. 2 in the Mondial lineup. While it is a competent unit, better than the Bedini, Hafler and PS Audio I had the opportunity of auditioning at that time, it is fuzzy and unmusical, when you compare it to top ranking brands of the same period. If you were looking for a solid state amp of the mid to late 80s vintage, I would suggest 1st or 2nd generation Rowland monoblocks. price point will not be staggeringly higher than Aragon 4004, but you would find yourself musically in a different world all together.

Hi Marty - I think we all have a more clear view into your budget....looks like the $500-700 range? The ARC pieces in this range are at two extremes: warmth and dimensional but lacking detail that I sense you are after, and the other end which is very analytical and flat. You know the CJ sound of this same time period and that has not worked. What about some of the older Classe or McCormack models? These units were consistently rated as a sound somewhat in the middle. And I have to believe many are in your price range.
