The Doug Sach's 2, DS2 should be in that price range and using 6SN7 tubes it is one awesome preamp. Doug has managed to master quiet power so that it doesn’t get in the way of the sound, and has found components that has the most minimal impact on the sound. After a lifetime of modifying Harmon Carden Citation and Macintosh equipment he found a design that is superior to those venerable tube component manufacturers. I have had too many preamps. Put Linlie E6SN7 tubes in the output stage and the preamp appears to disappear. He'll also match the outputs impedance to up to 2 amplifiers.
