This is the most affordable DAC I know of with I2S and XLR outputs, Bluetooth streaming, preamp capability, an IEC inlet (for a standard power cable), fuse drawer and remote control. It's also one of the best-measuring DACs.

There are a few minor marks on the chassis. (Which could possibly be cleaned off.) If I don't look closely, it looks like new.

It comes with the original packaging and accessories.

Price includes the PayPal fee and insured USPS Priority Mail shipping. USA only. If interested, send a message with your PayPal email and I will send a request.
