Quad lovers!
According to Boogie, they made 2800 Quad preamps between 1987-1992. I have serial # 1973 and it is an absolutely brilliant preamp. My beloved Quad blows my EXPENSIVE and rare Bogner Fish away. Actually the Fish is more of "The Hot Rodded Marshall sound that the Marshall factory is unable to produce" and therefore they are different preamps. The Quad is my alltime favorite preamp. So smooth, soooo tight and heavy!keep rockin!
