I just hooked up my super tube rectifier to my space tech lab preamp. What a difference! It made everything sound a level smoother refined all of the same time. I was a little leery about the whole thing but it was definitely worth the $1100. Amazing. The part that concerns me is that I don’t believe in power cord or interconnects or speaker cables making a difference from what I’ve read the rectifiers are supposed to make a difference. Anybody out there explain to me what these super two rectifiers do that have such a positive Influence on the Sound quality?
Tube Preamps Should Have This Feature
So it's late or you just want some casual listening for a short time. "Should I fire up my tube pre for 30 minutes?". My answer is "No". Why not let me flip a switch (or push in the volume control) to put my pre into "bypass" mode? Bypass would, effectively, convert your pre into a passive device, keeping the tubes dark.
This sounds useful to me.
