Thank you very much @lordmelton for the update interesting test. You have impressive gear and you use the best components, hence the high price tags :).
All in all you could easily spend upwards of $5-6k to fully implement the SOtM and that’s if you have a master clock already.
It will be interesting to know what you will try next I will follow your posts.
Perhaps the next logical step in your system is to try the Phoenix. From the reviews I found the quality of the Phoenix output beats everything else. Your Aurender A20 is 13000 euros 3000 more is not much in comparison. Getting it from the second hand market will save a lot.
