have you played with the impedance settings? That has always intrigued me.
I set them up as recommended by their supplier. You'll have to ask Jim and Mark Seaton and others how the sound changed when I took them out. Jim was saying that the highs were not what he was used to and thought the amps were to blame or something else. It could be the impedance setting on the amp cables, but the old cables sprung the highs back quickly and I could see the look on Jim's face. But for me the bass loosened up and the midrange got thin. So they are not suppoed to fully break in for 200 hours. And the highs are supposed to open up over that time, so I want to run them in this week to see.
I hooked just the DAC-Pre cable back up this morning and left the JPS cables on the amps and it was a good marriage of both. I think I will try the amp cables at medium versus low impedance setting to see if that changes things. All I can say is that these things really affect the sound in a good way and if the highs come back to ribbon status then I will be thrilled. The bass was authoritative and the modrange had depth and body like crazy. Plucking guitar strings never had so much "bass" content before. Very cool.
According to Joe Abrams, all cables smear the sound because all frequencies separate along the wire and then become spaced out versus aligned for arrival at the correct time. Those little black boxes supposedly realign the sound. Intersting to see the faces of the folks in the room when they knew I was changing them right before their eyes and that the sound changed so much.
