Yup I agree. The phono stage of your tube preamp gives a completely clean and silent sonic background.
this phono head came from the Pioneer SX-770 receiver and is of 70's vintage...
otoh, Jim Jagerman is a very capable designer according to Kevin Kennedy a co-moderator at diyaudio....
there are two types of phono heads out there, the first is the passive, type, and the other is the active type,
there are audiophiles who dislike active types because if the dreaded global negative feedback,
they like passives instead.....
but if you do not know the difference, then you need not worry, just listen and see if you like it...
i am going to make both types so people can compare......
