I don’t own any PS Audio gear except one of their power cables. I have been over to their headquarters for a tour. Nice people and I bet they are up to answering any questions you have. Here is a review of the PS Audio $6K offering. http://www.soundstagehifi.com/index.php/equipment-reviews/1028-ps-audio-bhk-signature-preamplifier
PS might let you do a buy/try.
I do own a Rogue Audio RP-1 and I am very happy with the product and there are a bunch of reviews on this product out there as well as the RP-5. The RP -7 is their flagship Pre and If you give them a call I bet they might let you do a trial on the unit. The RP -5 got some great reviews as well.

I really like the way the RP-1 softened up and breathed life into my class D rotel amp and B&W foor standing speakers.
