There are some stand-alone phono stages out there, which preclude the need of a typical preamp. They can plug right into a power amp since they have enough gain, and also have a volume pot. I'm looking into this set-up (I have no need for any other source), but wonder if there are units that have the necessary extra gain and a volume pot; and not have the selector switches, extra power supplies, and so on that come with the typical preamp. Something like a passive preamp, but not passive.
Is there such a thing? A 10-20 db gain box with a volume pot?
