I don't know how useful it is to call these $1,800 speakers. They're already widely available at under $1,000 and once the refurbs start flowing from the Harman mothership - it's on.
I heard these the other day and they sound a lot like my Betas which IMHO do more things right than they have any right to for their price. Infinity's engineers are among the best in the world, and that's sort of my problem with this (and other) reviews here: listening preferences aside, if given a choice between a small, internet-direct company with limited R&D or the deep pockets of Harman - I'm going with the design money.
In the case of these speakers, the drivers are remarkable. I've seen other reviews that comment on their smoothness, transparency, and value at their list price (which, again, unlike ID, is totally meaningless). I really do have to wonder if this isn't a simple case of rooting for the underdogs in the industry. A 2 for value, despite near flat frequency response, great bass extension (without the artificial impact some seem to favor), excellent imaging, and nice cabinetry? What exactly is wrong with this calculus? It sounds, as is the case with the Betas in my room, that they do almost everything right.
If you had entered this review thinking of these as sub-$500/pr floorstanding speakers (which is how much I'll pay for mine next year or the year after), what would you say? My only ID experience was with Aperion and I was not overwhelmed. The "cut out the middleman" lie is really only a means of price control. The build quality and parts/pieces are no better than Infinity, and the R&D is nowhere near as extensive.
Not trying to be mean, but this is a cheesy, half-assed review.
