"I do love tubes:"
Very nice setup! I also have the Fostex TH-x00, with Lawton mod, alpha pads, and the PeterEK detachable cable mod. Very fun sounding, but harsh treble that kills me on most tracks. Afraid they don't get much use these days.
If I'm every going to try tubes, it will have to be something that sounds great with the included tubes. I have no desire to get into tube rolling, too much effort and seems to be a lot of hit or miss on the tubes. Any suggestions on tube amp that would warm up the HD800S without requiring tube rolling?
