Rogue Audio Perseus Phono

Does anyone have an opinion on the phono stage built into the Perseus? I was thinking about running my Scout right into the preamp as opposed to outside phono preamp?
its phono stage is as good as many separates
I'm actually looking into the same thing. I have a PS Audio GCPH with a Benz Ace SL (low output MC), and just added a Rogue Perseus. It is much quieter though the Rogue Perseus directly. Honestly, the sound is big and clear...not sure the GCPH is bringing anything better to the table.
