Would a Sparrow be better than an Auzentech Forte (pci-e sound card) for headphone/2 channel music, movies and gaming? I have Denon D2000's for headphones. Thank you.

, but it relies on very noisy switching PSU of a PC.
Why does Digital Bitstream pop-up in the context of analog output head-amps?
Anyhow, no impact on digital is present. The analog audio output is affected, and that's when the PSU matters. A good audio power supply is typically linear and has noise measured is MICRO volts (http://www.amb.org/audio/sigma11/, see Technical highlights). Sigma 11 measures 12uV. As for ATX switching PSU noise specifications, see the section 3.2.6 of http://www.formfactors.org/developer%5Cspecs%5CATX12V_1_3dg.pdf. Note the noise figures are in MILLI volts... Perhaps onboard voltage regulators help, but they are have noise as well (for example, http://www.national.com/ds/LM/LM340.pdf shows typical 75uV at 12V).
If you re-read carefully, really carefully the statement "The circuity on the Auzentech sound card may be fine, but it relies on very noisy switching PSU of a PC." and think about the statement in the context of the original posting #661...
"You asserted that the PS in the PC would make a lot of switching noise and that would be detrimental to using the Sparrow out of the
PC."
Nope, I did not assert that. Again, the statement was "The circuity on the Auzentech sound card may be fine, but it relies on very noisy switching PSU of a PC."... for analog output. Has nothing to do with Sparrow.
Again, noisy PSU affects analog output from a PC audio card.
I done wasting my bits on this.

CEE TEE, the ad1852 has a jumper on it, switch the jumper to the other pair of pins for a little rolled off highs. The highs will become less harsh with time, but if still too harsh, I would recommend switching the jumper.

Wow, really? That's all great news...I have an option to try if the highs don't mellow out just a bit!!
Because Kingwa (Qing Hua, BTW) recommends around 150-200 hours of burn-in, I will do that and then if they haven't settled a little I will try the jumpers.
Thank you haloxt!
(So far, it is promising and I can't wait to listen some more this weekend...)
