Here are what industry experts are saying about Trends PA-10 Tube Headphone/Pre Amplifier
"...I inserted the PA-10 in between the UD-10 and the TA-10.2.P. The difference was immediately apparent! .... the whole system sounded much better balanced, It surprised me a little just how much improvement the change of valve made. In my original review of the PA-10, I hadn't found the 6H23n to make that much difference.".
