I own one but haven't used it in a while. I used it as a back-up to my SP10II. Harry Pearson of TAS reviewed it and made a comparison between its sonic signature and that of the SP10. Sounds quality is good but its build quality is, IMHO, poor, contrary to Shadornes expectations that it would be robust. The owners manual incorrectly identifies tubes or their locations or both, and manufacturer support was (is?)absymal. Look at one with the lid off, listen to it with the right tubes installed, check out all the functions to make sure they work, and make your own decision whether it will float your boat. If its not already apparent, IMHO, this pre-amp doesn't compete (successfully) with $5 to $10k stuff but if you want a small, cheap, pre-amp that sounds pretty good, check it out.
