Latest bulletin on the Yaqin tube buffer (and last unless someone has a specific question): I've now moved my best interconnects (Kimber PBJ) from elsewhere in the system to do input and output for the Yaqin. At this point the only difference they make may be in my comfort at having the signal treated the same on both sides of the unit, but what's the harm? More important for a few of you is that LP records sound even better with the Yaqin in the system and they sounded pretty good before. And last night the Met "Barber of Seville" I'd recorded on the SciAtlanta cable box from PBS Great Performances sounded great; the tenor's interminable final aria was like he was right in the room - but, thankfully, more than 8 feet in front of us.
So: Yaqin tube buffer heartily recommended to all music lovers.
