ARC LS 17 vs LS 25 Mk II


I'm looking for a new preamp and am seriously thinking of going with Audio Research. Given that these two pieces are very close in price, which do you think I should go for, the newer 17 or the upper level 25 MkII which is a bit older? I'm looking for good air, soundstage, transparency and decay.

If you want air, transparency and decay, the LS17 will win in those areas. The LS25mkII has more weight and slam though.

I'm an ARC dealer.
No contest,it's like comparing a Miata/LS 17 with a Corvette/LS 25.O.K maybe I embellished a tad.
Thanks Mark and Dave. So am I correct in saying that the LS17 sounds more refined, whereas the LS25 mkII has more low end authority? Damn, I wanted both :)
