I've not heard the Perreaux but I think the physical design and layout is outstanding. Looks like discrete dual mono circuit boards and the external DIP switches are favorable in my opinion. I find it disheartening that more manufacturers do not offer such flexibility. Cartridge selection is vast and they are not all rated equally in regards to interface. The ability to adjust the capacititative and resistive loads optimizes the cartridge selection to the phono pre.

I currently use a Michael Yee PFe-1 and know from experience that experimenting with various settings with a particular cartridge can yield amazing improvements. I like the way the Perreaux exposes the DIPs on the rear. I currently have to disassemble the cover to gain access to the DIPs on my current phono-pre.

However, I think I would have seperated the power supply from the main enclosure. Phonograph systems are so very susceptible to external sources of noise and interference. And the toroidal equipped power supplies on my hardware have a distinct "hum" that becomes more apparent with age.

However, I am sure the Perreaux engineers have thoughtfully considered the layout and that just isn't a problem.

I'd definitely be curiousto audition this piece if it were available. It looks well built.
