The best sounding Audio Research Line Stage preamp


I'm in the market for a used Audio Research Line Stage preamp and was wondering if anybody with experience on the following models could help me as to which you might feel would be the best sounding model. I'm after the ARC brand due to it's noted dynamics and clarity. It will be hooked up to a Classe CA-301 power amp and a pair of Magnepan's 3.6R speakers. These are the models I'm considering. The LS2B MkII, LS3B, LS5 MkII, LS12, LS16 MkII, LS22, and the LS25MkII. Thank you for all your help.

Please forgive me for hi-jacking this thread. Since this thread seems have attracted a lot of Audio Research enthusiasts, I thought I might inquire about another, albeit more modest Audio Research offering; the LS 8 Mk II. Any thoughts or opinions on this less ambitious model?
