A moderate priced dac

The Schiit Modi 3 is an awesome bare bones DAC.
Pay more money if that is important to you one way or another.
But you may be very surprised by this one,

A excellent natural sounding dac Audio mirror, and has 
a Lot of options.$1500 and up is very good especially 
for a vacuum tubedac  and madein U.S.A.

If you want a dac that would compete with dacs under $10k for features and sound, look at the ps audio DS jr. what other dac is fpga based, has Ethernet built in, is a Roon endpoint, can hook up directly to an amp (does sound better thru a preamp though), has i2s inputs, and you get free firmware upgrades twice a year that can add functionality (like MQA) and improves the sound quality. Plus, it sounds fantastic. I owned 1 for a while but moved up to the DS sr.

Buy the MF DAC and send it to me for upgrades.  Nothing listed above will compete once I get my hands on it!

Happy Listening.

Are you talking the mf v90 and what do you do to it and cost?
