Tube suggestion for Jolida JD-100

I have tried two other as well. An Amperex 12AX7 smooth plate and a GE 5751WA Triple Mica Black Plate. The Amperex had a soft atmospheric quality to it. Pleasant but lacked inner detail and focus. I tried the GE based upon Joe's Tube lore. This proved to be an interesting listen. I was concerned about the reduction in gain with the 5751 but this proved to be an non-issue. With this tube the backround and space between instruments is blacker. Dynamics are improved, with a tight tunefull bottom end. Focus is clear without being edgy, the midrange is open, airy, and smooth. The top end has extension but is clean. This tube is a step up from any of the others I used so far. On top of that they are cheap, $8 bucks a tube.

I have tried three different tubes. The stock one, a 1961 NOS Sylvania and the Sovtek 12AX7LPS. The Sylvania was a disapointment, grainy, aggressive. I think the unit sings with the Sovtek Long Plates. With these tubes the CDP has the attributes you are looking for.
