What is the quietest preamp you've used?

Solid State - KLYNE AUDIO ARTS 7LX3.5/B using balanced
Tube - FIRST SOUND

Herrons. Take your pick of model, tubed or ss.

I've had mainly tubed preamps for the past few years including the First Sound, the Rogue, a Joule-Electra LA100 MkIII, CAT.

I wouldn't call the Rogue 99 Magnum "quiet", although it's nice sounding and certainly quieter than the two versions of the 66 I had.

My First Sound Presence Deluxe MkII was indeed quiet.

My current preamp, the single ended, tubed Herron VTSP-1, is the quietest preamp I've ever heard, other than the cutom built ss CTC-Blowtorch. I love my Herron.

Among tubed preamps, I doubt that there is anything much quieter than the First Sound. The ear-to-the-speaker test yields absolutely dead quiet at normal listening levels. There may be solid state units which test quieter, but I doubt that the difference could be sonically significant. Great dynamics and low-level detail out of the First Sound due to its quietness.

The quietest is ALWAYS going to be a passive device. You just can't beat that for transparency. However it has other shortcomings that are generally bettered by active stages.

Enjoy,
Bob
