Wmcmanus,
Thanks for the link to that thread. You're right, it is QUITE a journey! Just when I think that I've gone off the audio deep-end, I see the dedication (obsession) of audiophiles like that and it puts in all in perspective:o)
I plan on tube rolling the ZOTL in the near future, and this thread gave me some great ideas on where to start.
Regards, Mark
