Dave,
I plan on getting the Sierra 1 Towers when they are available. One of the things that's been on my bucket list is a tube amplifier. (That's all that we had when I was kid) Would a Rogue "Cronus Magnum" tube amp 90w/ch be compatible with the towers? I can't think of why it wouldn't be but I thought I should ask anyway. If not I'll use my old trusty NAD instead.
Thanks!
Tom
