Product Reviews
Great tube! Sound stage is wide with lots of air and 3D. Running the TAD 12AU7 in a Black Ice Audio FOZ Sound Stage Expander (SSX). It's the first tube in the amplification stage after the phono stage so it has to be good and balanced otherwise everything else won't sound right. Before the TAD 12AU7, I was running a very nice NOS triple mica black plate tube. The TAD 12AU7 is as good, if not better than the NOS tube.
