Hi Thedautch, I have used both the Quattro fil and the 1030. I felt neither of these ICs to be any better than the Coincident ICs. Then I saw the Sakura OTA thread and thought I would give there wire a try. IMO,the OTA ICs are not just different but outperform the above mentioned ICs and all other ICs I have heard at a fraction of there price. Don't let the price or the looks of this stuff fool you. I just replaced several thousands $$$ worth of wire for this silly cheap looking stuff. This is one of the best audio moves I have ever made. Please read the Sakura OTA Kit thread.
