I just picked up this CDP and it has stock tubes. A poster on Audio Review suggests that Amperex 12AU7PQ for the voltage gain stage and Radiotechnique 12AU7 for the output buffer. This to get both lush midrange and better top end and base. I would appreciate hearing from anyone who has done something like this. Thanks for your help. Dave
Ive tried many 12au7's and found great success in the inexpensive Jan Philips 5814a for 7 to 12 dollars a tube. Lots of air snd detail, a real pleasure in my Jadis. Im sure the PQ Amperex is a nice tube but give the Jan a try before you drop some big $$. Best of luck!
