I hate to toot my own horn too much but I just can't contain how amazing these turned out! I had posted before about the new Clarity Caps CSA Series I tried but I also tried several new things at once so I can't really nail down what made the difference. The other upgrades were Vampire Copper RCA's, Mueller Copper binding posts, Neutrik PowerCon AC connectors, and Vishay Z-Foil resistors at the input. While they sounded good at the start I've been playing pink noise through them for a few hours every night for the last few nights to kinda help break in the caps. Last night I sat down to listen to them and my jaw hit the floor! My speakers vanished and I was hearing a level of clarity I have never achieved before. At least from an amplifier. These are essentially single channel versions of the ST35 but also including Dave Gillespie's EFB circuit. I've already decided to upgrade similar parts in my SP13 and ST120. All I know is that these things sound better than they have any right to for around $500 in parts!
