Thanks for the information regarding the tubes and how to set them up. Besides the sound and the philosophy behind the GG, another unique selling point for me is the fact that it is upgradable. dCS does offer firmware upgrades, but being able to keep up with Lampizator with all the new hardware build into your existing DAC is one that weighs really heavy for me.
The key thing is the DHTed Lampi lets you put the best valves in audio at the top of the electronics chain. Lamm, Jadis, AR, and other valve electronics that come in down the chain are great but do not have this level of valves
