I like MIT with my Krell and Maggies, very much. MIT doesn't really just "smooth" per se, it resolves more dynamic contrast than any other cable, period. I mean that...show me another cable that is more dynamic (that is, there is more loudness difference between the very quietest to very loudest sounds on any recording). There aren't any other cables that do this as well, I've tried/owned a bunch. It makes all the instruments in the soundstage much more closely approach the "weight" that they have in real life. Also, it doesn't really "roll off" the treble much at all. What it DOES do, is prevent the treble range from leading the mid/low range in time. This effect is the primary reason tube amp lovers can't stand solid state amps, IMO: They haven't heard solid state with decent MIT cables. I have a tube amp, too, and have heard this effect...the problem is that the MIT speaker cables I have don't work well with the tube amp, but one of the MIT interconnects almost does...depending on the speaker cable I use with it. And yet, some of the silver cables I've tried/owned also "almost work" with the tube amp....
Some of the biggest audio places carry..
Stores that are ultra high end like Goodwins Audio And Overture Audio and Progressive Audio and many others seem to carry Avalon and Spectral, They seem to prefer it to all the Krells and Levinson and Pass and Conrad-Johnson And Audio Research, which more of these stores also carry. They all of coarse carry MIT. I think that when you get into ultra high end it becomes more a factor of buying as a system. And I think Avalon/Spectral/MIT are some of the best sound money can buy. Anyone agree? Spectral gear is very analytical, but when their hooked to a laid back Avalon, and "smoothed" out by MIT, their the most detailed sound out there
