I have changed the output tubes from the Electro Harmonix 6922 to Mullard PCC88 tubes and notticed a deeper perspective and better LF reprodution. The euphic coloration is reduced and the balance is better, esp. when playing classical music like violin.
Later on I changed the regulator tube from a Russian to a 1962-1965 NOS Mullard ECL82 tube and the sound qulity was even more refined. Most music sounds detached from the speakers and the perspective is deeper.

Hello to all,
I have the New Dac is my system, testing it. It is almost done so I am breaking it in and I can tell you, WOW!!!!
The unit uses a NOS Dac (Analog Devices 1865N) chip and they employ a 1x Oversampleting filter.
The unit uses tubes in both the output stages and in the analog power supply. As I break it in I will use the stock tubes and then roll to my vintage tubes.
So far I am so pleased with the musicialty that I am rediscovering my CD collection.
More to come.
