This 6922 tube type was rated the "best buy" by Vacuum Tube Valley magazine in their 6DJ8 / 6922 tube shootout. They cited a better bottom end and "less offensive" high frequencies as two of the reasons for their choice. This is also the same tube which is sold by Richardson's under the Bugle Boy brand name.
