Conrad Johnson Sonographe SC-25 & SA-250
SOLD
This is a great sounding pre and power and imo very underestimated in the U.K.
I’ve had some nice gear over the years and this beats them all but the itch has been scratched and I’ve now moved on to hybrids .
Top notch build quality
There is a very small scratch on the top of the power amp ( which I did but I don’t know how) and a small mark on the fascia .
I have recapped the SC-25 .
The knobs on the pre are not the correct duck billed one but I’m confident that they are from another Conrad Johnson preamp.
The serial number on the pre says sc-26 ?
They both operate flawlessly .
