Emotiva XDA-1 DAC?

I use the BB OPA2134 as a headphone amp.
For this use, a little 'opamp rolling' may yield benefits.

As it stands, would the DacMagic for maybe a 'c' note more, be an improvement?

FWIW, tried the XDA-1 but eventually settled on the Eastern Electric Minimax which was markedly better. Thanks all for you input!

After a whole month of break in, I spent the past 2 days listening to digital music and am pleasantly surprised to find no "digital harshness", just music... Been listening to Pandora Music thru a Sony PS3 to my new XDA-1 via optical link, connected unbalanced to my amp, PS Audio Hca-2, driving Ambience Superslim 1800SE... At initial set up the sound was promising but a bit harsh and the mid's sounded metallic... 200 hrs of break in later the sound became more musical and the midrange less harsh but there was still a metallic edge to it... Now, am just enjoying the music and am truly happy at how the XDA-1 delivers the goods. No harshness, no digital glare, great sound and good music... WOO HOOO....

Anyone know how the XDA-1 compares to a Vdac?

I've had the XDA-1 for a few months now and I absolutely love it. I have it in a minimalist computer audio setup listening to 24/96 and 24/192 files from HDtracks.com. The XDA-1 directly drives our trusty Adcom GFA-535 MK II via LAT international silver interconnects. The Adcom is directly driving a pair of Pioneer bookshelf speakers. The sound is, quite frankly, breathtaking and free of fatigue. I can and have listened to music over this setup for hours at a time and have been completely enthralled. The remote is solid and built like a tank. The display is beautiful and classy. The entire unit looks like something which should cost $1,000. Emotiva really has outdone themselves with this piece of gear. It has a very high wife approvement factor and the simplicity of use is appreciated. The XDA-1 negates the need for a preamp so if you truly want a simple and clean setup then this is your best choice.

Heartily recommended!
