Audio Research Reference One Preamplifier - One of the original super preamps.
This is a later model with detachable power cord and Infinicaps.
Comes with Electroharmonix 6922 tubes but you can tube roll to your heart's content. I simply do not find the need to do it.
Lots of inputs (accepts RCA and balance XLR connectors for all inputs).
Three sets of unbalance and balance outputs via RCA and XLR connectors.
Beautiful sound - detail, speed, spaciousness. Truly high end.
I would keep it to go with my second system but I simply have too much equipment and really need to thin the herd.
