In the April-2014 Stereophile published reviews of DacMagic XS and Audio Engine D3. So they compared each other and made some comparisons against Audioquest Dragonfly. It seems that Streophile people preffer the DacMagic XS over the other two. In fact, these 3 units are "Stereophile Recomended Components” with B classification).
Well, I'd like to know if somebody has compared these headphones amp/dac against the Nuforce Udac-3. This one has an asynchronous USB, support up to 96khz, and so has DSD capabilities. Finally udac-3 has a volume knob and two audio outputs (¡a good idea!): rca stereo output and coax digital output.
I want to buy one of these, however I can't compare all of them, so I don’t decide which one to buy. I like the idea of having volume control independent of the computer volume (XS and uDac-3), I like to have usb asynchronous (all of them), it could be interesting to have 192khz (I have flac files 24bit/192khz, but I have my doubts that this is an audible feature). Finally, having rca outputs and/or coax output may be nice in some circumstances.
I have grado sr225i headphones, it seems that all of these amps would work fine with it. For me the most important question is: ¿which one sounds better? Nuforce is chepear, Amazon Price is $125. XS and D3 Price is $189, Dragonfly Price is $150.
What do you think?
