I used to own the DJH preamp with 2 different SS poweramps (Linn Klout and Pass Labs Aleph 30) and its 20 db gain had me clipping the amps at 11 o'clock. I sold it because it had little volume control adjustment, even if it did sound awesome.
This preamp was designed for use with the Sixpacs. I think it would also work with the earlier Rocket 88 (non R). I liked the DJH pre a lot but feel it still won't work with the new Superamp 2 that I now own. I would call Cary's tech suport (same for AES), and ask about a recommended mod for it. 919-355-0010 They are up on this design.
