Many thanks for the "Tube-o-lator"... It has now been over a month and the effect is quite clear! I have usde it inside my DAC, and Pioneer Universal disc player and the results are excellent. Complete lack of "grain" in the sound compared to before: This, combined with max Townshend's latest 3D seismic sink means that I am now getting a sound from CDs which is perfectly acceptable (given a well mastered CD) and compares very favourably to analogue. I would use it in the phono stage but the phono stage in my Audio Note amplifier uses valves and has no chips or ICs!
.. Thanks very much!
