I'm really enjoying the QuteHD DSD dac paired with the Off Ramp 4. Sounds very full, robust and organic with excellent imaging. The OR4 adds more weight and clarity. Everything sounds more focused and I didn't know there was so much smearing going on. I'm convinced that a high quality USB converter is a necessity for computer audio. This combination is closer to what I'm looking for versus what I was hearing with the Overdrive alone.
My only complaint is that on some recording with female vocalists, the treble sounds a bit hot. I'm hoping to address this by adding an external power supply to the QuteHD. It comes with a cheap wall wart. I ordered a decent one from MCRU here: http://www.mains-cables-r-us.co.uk/power-supplies/514-chord-qutehd-linear-power-supply.html
It's coming from the UK and I'm in the USA, so it'll arrive next week. More to come then....
Another solution might be warming up the sound from the Dragons. If I wanted a warm sounding 300b tube, which would you recommend?
Thanks,
Ernie
