Greatly improve with another tube? Greatly? I mean its already pushing my cans to subsonic frequency with incredible control and the top end is like some kind of quantum microscope, every grain of billions of grains of sand, all perfectly defined. Toe tapping drive and verve and dimension. Describe how it would improve so much with another tube, greatly is a powerful word. This amp is jaw dropper as is. Thanks!
(I do plan on going on a tube spree, so I guess I'll find out.)
