Benjamin from Mojo Audio again...
I did want to mention a few things about our Mystique Y.
First of all, Mitch has the middle-priced Mystique Y AM with amorphous core chokes. If he had our Mystique Y NC with nano crystal core chokes the sound quality would have been even closer to his Mystique X NC Z.
The reason is that aside from the single USB input and the AD1865 vs AD1862 DAC chips, the two DACs are nearly identical: identical USB input...identical power supplies...identical direct-coupled class A output stage...identical component parts quality...nearly identical chassis.
MSRP on the Mystique Y AM that Mitch has is $5,499 whereas retail on the Mystique X NC Z he has was $12,499. So the Mystique Y AM is less than 45% the price. Our entry-level Mystique Y Fe with ferrous core chokes is only $3,999 which would be less than 1/3 the price of Mitch's Mystique X NC Z.
Quite an exceptional value if like most of our customers all you use is the USB input.
