Interesting question. For me, they simply make Maggies live up to their potential even though I do use a SS on the bottom end right now. I would prefer a tube amp there as well, but will have to save a bit of $ to get that D-76A on ebay right now.
No fair anyone buying it until I can! I call dibs on it!
Oh, if you want to buy it and send it to me as a gift, I promise to give you all the credit here on the Forum.
Cheers!
