Infection, Sorry for the misunderstanding, but "PS" is most commonly used as an abbreviation for Power Supply. Since you've apparently relaxed your yen for balanced outputs, all the other phono stages mentioned are superb. In my second system, I use a Manley Steelhead, the big brother to the Chinook. I like it very much.
I once looked long and hard at the K&K preamp (which is also full function but can be used as a phono stage, like the Atma-sphere units), because I wanted a balanced circuit and I like building stuff. (You can buy it as a very flexible "kit".) It has a good reputation, but I've never heard one. But if you choose among Herron, Manley Chinook, and Aesthetix Rhea Signature (see below), you cannot go "wrong".
I briefly owned an Aesthetix Janus, their version of a full function preamplifier that contains, essentially, the Rhea phono stage inside. From that experience, I strongly recommend that you look at the Signature version of the Rhea, not the less expensive non-Sig version. The capacitors of the non-Sig Janus were of a quality level not commensurate with what that circuit can do. (Dare I say they are crappy?) Upgrading the capacitors in the non-Sig Janus resulted in a huge improvement in sound, really improved it from unacceptable in my opinion, to very good. The Signature versions of both the Janus and the Rhea come already done with much better capacitors, among other improvements to the non-Sig versions.
