Opinions on Audio Research LS17 & LS26

I demo'd the ARC 300.2 amp and ARC LS26 preamp in my system (Ayre CX7e CD player; ARC PH5 Phono preamp; Linn LP12/Ittok LVII/Lyra Argo/Lingo; Wilson Audio Sophia Series II loudspeakers; Shunyata Hydra 4; various cables including AQ speaker cables and Cardas Cross XLR interconnects). The LS26 is a wonderful preamp and will be the next one that I purchase when I can afford to do so. It is a champ at soundstaging, is very neutral in my system with no sonic signatures of its own, & pardon the cliche, it just gets out of the way of the music. I cannot speak to the LS17 because my dealer did not have one in stock.

In addition, I also found the folks at ARC wonderful to deal with. In particular, Leonard was always helpful and accessible whenever I had any questions.

As always, the best way to know for sure is to demo the preamp with your system to ensure there is system synergy with the rest of your gear. Best of luck with your purchase!

I have a Ls26 and a 300.2 ,a cd mk3 and the very revealing, proac 1SC's. The LS 26 is incredable.A hugh wide and tall soundstage. no coloration .Does everthing better than anything I've heard before.

I have a LS26 and love it. This is a somewhat different sound from Audio Research products.The 26 is very close to the Ref, just a tad bit smaller in its presentation. This is the best buy in their new line IMO. This is a great leap ahead from their past preamps. The new line is the most organic sounding,lots of air, massive soundstage, as deep as it is wide, which just floats into your space. I really enjoy the decay, which just goes on and on and creats an effortless, carefree, relaxed feel.
As I understand, the 17 sounds the same, again just smaller and with a few less features. I have not heard the 17.
