CH Precision C1 DAC-Preamp

Any of you listened or own a CH Precision C1 DAC-Preamp with the separate power supply and streaming option ?
I'm interested into this gear even though it is extremely expensive.
This DAC can me mated to a power amp and stream directly from a NAS.
I've heard it's one of the best sources out there.
Please share your experience if you had the chance to listen to this gear.
Hey Theliste,
Yes, using the c1 with streaming option as well as through cdp via coax.
It is amazing! Will be trying the x1 power supply next week. Really excited to try it out.
