There is a very high end turntable company that is located in Memphis TN that has bought several of the Corelli and phono boosters Perhaps you could contact them for a reference.
Merrill Williams Audio LLC
1722 Chelsea Ave.
Memphis, TN 38108

We have literally sold 100's of the Phono Booster and the Akiko Corelli's but we can not just give out end users email address without their permission..
Depending on where you are located, The Cable Company and Jaguar Audio both carry Akiko products in the US.
As I said previously, I think Audience makes very good conditioners but I do prefer a total passive strip versus Teflon caps with the Corelli. Although both locations would benefit a Corelli, your front end would be the best location, preamp, CD player and turntable location.
