Hi! I'm interested in purchasing one of this amp/dac unit, when they'll put it back on sale, but i don't know whether to purchase it with tcxo upgrades or not?
My questions are:
-The tcxo upgrades are necessary?
-Does it change sound? Or by adding more to the circuit the sound becomes less transparent?
-If it's required a 80 mhz for the dac chip why does it needs a 12 mhz for usb ( when u plug it from usb), from coax/optic the 80 mhz makes sense, can i purchase just the 80mhz and achive the same thing?
I'll pair this amp/dac with sennheiser hd600 (i hope it'll be a good match).
I'm not a tech guru, so sorry for so many questions.
