Audio-gd Vacuum HE1 XLR Tube Preamplifier Review - HomeTheaterHifi.com the best pre this reviewer ever reviewed.....and I can vouch for that.
Spatial Audio Raven Preamp
Spatial is supposed to be shipping the first "wave" from pre orders of this preamplifier in May, does anyone have one on order? Was hoping to hear about it from AXPONA but I guess they were not there. It's on my list for future possibilities. It seems to check all my boxes if I need a preamp.
