I have an awesome sounding player dac from Tube Technology with a digital input via BNC or optical. You can get a BNC coax adapter so that it will work with your coax output. It's an awesome player with the same dac section as the Chord DAC64 and a tubed output. They don't come up often so if you see one jump, like I did! I doubt you'll regret it, there's a review in HiFi+ magazine if you can track a copy down. Happy listening!
