What is the quietest preamp you've used?


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

Audio Research LS25 "Balanced" So quiet it was scary.
Plus it was the BEST pre I ever had.
My Rowland Coherence II. It is battery-powered and dead quiet. It is a fully differential balanced design.

You pose a very important question. It was not until I lived with a super-quiet preamp that I understood the importance of noise to a preamp's performance -- low noise is crucial to high performance in a preamp.

Creek guarantees it to not affect the music one bit.
Totally passive unit.
