Tube rolling with the 845B from Shuguang
by Roger S Gordon

"The sonic differences between the new Shuguang 845Bs and the standard 845s are not subtle. 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. Buying a matched pair of 845Bs for $150 seems a no-brainer to me. The 845Bs give tremendous bang for the buck. The only downside I can see is that Shuguang is supposed to release a metal plate 845 (845M) before the end of this year. Metal plate 845s are supposed to sound better than any of the graphite plate 845s, including the 845B. I hope the 845M becomes a reality, but in the meantime, if you have an 845 amp but don't have the bucks to buy NOS 845s, I suggest that you spend the bucks you do have on the Shuguang 845Bs."
