BLEMISHED (B stock) means absolutely new, but with minor cosmetic defects unless otherwise described. Same as new warranty!
CONSIGNMENT means used and being sold for a 'client' - guaranteed to work upon receipt at your end - typically there is no warranty unless it is expressly offered. This is an "as is" purchase.

PasPro 1 in Hafler DH-101 Preamp
This is a demo we built with an Elite Level Line Stage(a bit beyond perhaps), Toroid transformer, two pair of CMC Gold RCA Jacks and Alps Blue Beauty volume control. The board is graced with Japanese-made Takman carbon film resistors, Nichicon Audio-Grade power supply caps and a MOSFET power regulator for the B+. The heater voltage is also regulated. It’s a perfect piece for the listener with a single source. Of course the other high-level inputs work fine too. We can add a few more CMC gold connectors to your request.
As you can see there is a bit of added customization in the power supply. This is a superb sounding unit provided with a JJ E88CC tube and accepts any 6DJ8/6922/7308 or other tubes from the family. It has approx 24dB of gain but the stage is feedback free so it will need a gain matched tube to strut its stuff. It doesn’t just need a loving home, it will make that home ‘loving’ when you hear it. Sells for $795 including free UPS Ground/insured shipping for ‘lower 48’ states. See more here.
Sold! Buyer loves it!
