Audio Research LS-15 Infincaps - Audiogon Discussion Forum

Yet, overall, I thought that, at least in my system, both of the ARC LS15('s) had a more open, natural, and believable sound. Jafox does have a good point however, and one which would be a very big step up from the 15 and 16 in going to the LS5 of any iteration,( Mk1,II, or III) especially with the GNS mod. That would be a clear winner sonically

Audio Research is a great name, but I'm happy to say what everyone else is avoiding here. The LS2 is no better than average. Actually, that's overstating. It's actually far worse than average. Changing the tubes, capacitors, wiring etc. won't make it what it isn't. Put the fucker on eBay and watch the lemmings line up.
