Thoress Preamp

Does anyone have direct experience with the Thoress preamp? IF so, what have you compared them to and what system do they live in? How is the Phono pre in it?
Was reasoning about getting one into my system to drive Quad 57's in a smallish room (11 x 13). Like Jazz/female vocal etc.

Just got Thoress preamp best i have ever had wonderful stage ,great imaging,quiet very well made.One of the best!

Do you know what the output impedance of the Thoress preamp is? I looked at the PDF on their website and they only give the input impedance. Thanks.
