FS: Audio Research SP-12 (Refurbished)

This SP-12 sounds better than the stock Audio Research SP-6E I used to own back in the day. The SP-12 is basically the same topology as the highly regarded SP-10 in a single chassis. With the re-furbished power supply, the cap storage was increased ten fold. A very nice sounding preamp (especially at this price). Logged Freo-1 Volunteer Posts: 3183
