Re: Are Salk speakers in the same category/league for sonic excellence as say, Revel, Focal, KEF, Elac, B&W, etc.?
I think they are very good. Jim Salk is a true gentleman and the quality of craftsmanship is second to none. I've heard his offerings at numerous shows and even had a set here in my house for a local audio club meet several years ago. (His shop is here in Michigan - about a mile from me - and he was very generous to loan a set of SongTower RTs for a quasi-audition/demo for our gathering.) While I don't own his speakers at the moment, I do think they do compete with the best and I would encourage you to either contact him directly or see if there are any locals near you who have them who would let you come by for an audition.
And if you're going to be at Axpona in a few weeks, they'll be in rooms 570 and 384, too!
