Reviews:

 Hi Jim! :) I finally got to set up the preamp over the weekend and WOW is it excellent!  The look/feel of the jacks, casing, controls, everything.  The sound is first-rate; nice authoritative lows AND sweet highs.  I was making an unboxing/texting video as I unpacked and am going to post it soon...I am so happy I made the plunge for this preamp.  First-rate!
