What is the quietest preamp you've used?


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

The most quiet was my old (now almost 23 years) Perrauex SM2 bought in 1983. It was a slim design and was a highly regarded pre amp. Although extremely quiet with almost no noise or hiss... with comparison by todays pre amps its most likely anything but neutral.
