Almost criminal not to have pictures, Gaius.

Unreal!
Stone cold, the NAC 12S is naked as its case is in the body shop for restoration, the 110 has been powered up for 2 hours and is driving the 12 directly.
I mean astonishingly good and I know it will just get so much better....
I had a 110 and a 140 side by side, with ISTR a 52 providing preamp services. The 110 seemed lighter but more agile on the bottom end, whereas the 140 was fuller, warmer an very slightly slower-but still managed to time up a storm. I really couldn't tell much power difference into the speakers at the time (modified Advents).
According to JV in an interview there was much variability with production in the early days and not unusual for their "best sounding" preamp to change with any given batch at least back in the CB days so a 32, 42 or 62 could come out on top (or not ;-)
Regardless, enjoy the new/old puppies Mark!
