Thanks for the tip on the Quarts. A few weeks ago I found one pair of the Quart 805s for $129 so I pulled the trigger. I must say they didn't impress out of the box but after a few hours they've relaxed significantly. Well worth the money and built like a tank. They're hard to find but are a good choice for <$200.
I'm using a modded Quickie driven by another preamp. I have the parts to make a White cathode follower 5687. Of course, Crack is the next BH step.

Glad I could help Alan. They are a nice phone for the price. I find them a little bright on some material but they are fleshed out with a good bass response so they dont sound thin and bright and I dont find them fatiquingly bright. I think they are a fine match with Crack. In fact, my biggest peeve with them has nothing to do with the sound, as I mentioned, it is the Vacuum cleaner like cord. I need to see if I can do something about that, but you are right, they are build like a tank and that cord is as well :-)
