I purchased the Savant back during the big Winter sale, but only got around to really listening to them now. Sure, I put them on once or twice before, but not enough to get to know them. Now on a work trip, I can devote some real time in the evenings to the Savant. I don't know about mental/mechanical break-in for my essentially new Savant or X5, but about 2 weeks into my trip I'm really starting to appreciate this IEM. Instead of jazz, I decided to kick in some other genres like the Blade & Higher Learning soundtracks, Bombay Dub Orchestra, Groundation, etc. and the Savant was shining. One can sit there and pick out the flaws of any IEM, but this one to me appears to me the one that is all about a toe-tapping intimate experience. Not overly analytical, but sufficient resolution. Not too much bass, not too little. Treble sounds good to me. I am getting a nice seal with the Aurisonics medium SureSeal tips. I had the old K10U and though not at the same time as the Savant, I might choose the Savant for it's 'attitude'. Maybe next sale I'll spring for the latest K10U to do a proper comparison . When I get back to home base, I'm going to try the Savant with the Liquid Carbon, though that might be overkill. I'm curious to how the Savant will sound with better amplification. The X5 amp is good, but it's no 2Stepdance or Portaphile, some of my favorites. People using the Savant with the Mojo?
