What is the quietest preamp you've used?


Can you also please tell me whether you were using balanced or se ins/outs? Thanks.

Rogue Magnum 99 pre amp with RCA outputs, and my Manley Stingray (integrated amp)was so quiet at full volume you had to have your ear 4" from the speaker to hear any hum. So a vote for Manley stuff being quiet...
