One last update to this thread. I received the Mapleshade cables last week an have put about 20-30 hours on them, both movies and music.
I have tried MIT Terminator 2s, Cardas Twinlinks, homemade twisted pair magnet wire speakers, and now the Mapleshade Clearviews. The Clearviews sounded better than the other three right out of the box. The upper- mid region is extremely smooth and even aggresive sounding movie soundtracks are bearable (if they sounded too smooth I would suspect the speakers were missing something!). Well recorded movies with good music content sound really nice. I watched part of Crouching Tiger last night and the drum compositions playing behind the fight scenes were so good they distracted me from watching the images. Voices sound incredible as you would expect from this design.
My acid test CD for upper midrange nastiness testing is the Bill Frisell Quartet disk. It has some very tight harmonies (sometimes dissonant) involving trumpet, trombone, violin, and guitar (check out "Convict 13") that spotlight any brightness or other problems in this region. When I was first breaking in the TS-1, using MIT cables and cheap EL-34s, the sound would literally penetrate into my skull (OK, maybe not literally) during certain sections. Ouch! After break-in, and all of the system changes changes documented in this thread, and now the addition of the Clearview cables, the sound is fantastic: smooth, detailed, dynamic, very listenable.
If you have the Omegas definitley consider the Mapleshade cables. This is a great combination.
