Here is a review I found:
Reviewer: Anonymous Person from Seattle, WA United States
These tubes are wonderful. They are musical without being syrupy. They have detail and openness. The bass frequencies are reproduced well, and voices have nice timbre. At this price I think it would be hard to find anything comparable. I am very pleased!
