“Decided to experiment with these Mullards in place of the stock Chinese tubes since I had very good experiences with these tubes with my previous preamp. I only changed out the two middle gain tubes which have the greatest effect. They changed the sound noticeably. What I perceive is a shift toward more bass and maybe a bit more high-frequencies relative to the midrange. The jury is still out whether I will put the stock tubes back in, but these tubes sound good, just a little different.”
