Like the Positive Feedback review says, the difference between the standard Shuguang 845 tube and the Shuguang 845B tube is not subtle.
In his review Roger Gordon says, "To summarize, the advantages of the Shuguang 845B tubes over the standard Shuguang 845 included less noise, better handling of low frequencies, a smoother, more natural sound, and greater detail... It is like going from a $1500 preamp to a $4000 preamp. You can enjoy the music through both, but once you have heard the $4000 preamp it is hard to go back to the cheaper one.
Tube Matching Information: These tubes are packaged in boxed sets of two (matched pair). You need to order "2" tubes to receive this boxed set. If "Single - White Boxed" option is selected we will send un-matched tubes in the quantity ordered.
