I am ashamed to admit I did'nt build it, but the K&K is the best stage I have had in my system. It is quiet and abolisherd the RFI problem I had experienced with every other stage I have had. Nice sound , but not lush and tube like, good across the frequency exchange. As a bonus, Kevin is great to deal with. I don't know why, but the owners of so many small US companies seem so good to deal with, Tyler, Daedalus, K&K, Ridge street, all were patient and very helpful. Perhaps it's because they are all enthusiasts too.
