I am "between" pre-amps right now and auditioned it in my system. It wasn't right for me. It is rather sensitive to the input impedance of your amp; in my system it sounded rather lifeless. Also, my system uses all Ayre sources, so the fact that it is single ended really should have been a sign that it wasn't the right choice for me. That said, it is quiet, seems well made, and is quite nice to look at. But it will be a question of system matching, like with most things in this hobby.
BTW, I assume "SS" means solid state. The RP-1 is tubed. (http://www.rogueaudio.com/Products_RP1.htm)
