FIRST IMPRESSIONS: Nuforce uDAC USB DAC AMP with line out and S/PDIF out - Page 7

post #91 of 1841
haha..i think here only nuforce and HeadphoneAddict knows what chip they used

Could it possibly contain the es9022? ESS Products - DAC
post #93 of 1841
It could be something from ess which is why I joked that it was a sabre dac. I read somewhere about nuforce and ess doing dacs for oppo dvd or bluray players or something of that sort. I didnt read the whole article though.

The second dac from that link could very well be what they are using or at least very similar to that by looking at the fact that it produces a 2Volt out from a 3.3Volt source

Maybe Larry didn't set his to full volume so that he could get matching outputs with other dacs he was comparing with like the pico. After all, at full volume the udac will sound louder than most other usb powered dacs because of its 2 volt output.
Right, it doesn't need to be at max to match the Pico DAC-only line out levels, and the uDAC volume knob can go even lower to match the EF2's DAC when I was comparing DACs.

And, with the EF5 amp having a little bit of channel imbalance at very low volumes I can get the amp's volume knob up higher and out of the problem area by turning the uDAC down a little. I used to do the same kind of thing with the volume knob on my apogee mini-DAC. I've even been known to turn an amp up to 3-4 o'clock and control the volume of my amps entirely by using the Apogee mini-DAC's volume. The uDAC allows me to do the same thing.

The uDAC is a bit better than the iCon Mobile - being more refined, spacious, balanced, and extended. They don't really sound alike.

A good dac with a passive variable out would probably also open up the idea of having monoblock headphone amps to drive some cans with By the way, are there any power amp only headphone amps without a preamp section?

Not that I know of, unless you are using a Red Wine Audio 30.2 to drive the K1000.

hehehe k1k is a different story since they can run off speaker taps Well lets just not go as far as looking for monoblocks. What about just a plain stereo headphone power amplifier without a preamp section so that we dont need to separate the left and right of the headphone plugs.

When it will be available at nuforce-europe?
post #101 of 1841
The amazon link ships worldwide by the way

Thanks for the heads up. I'll set it to max and see how it performs.
post #103 of 1841
So, does this also do optical out?
post #104 of 1841
Only RCA coaxial out.
post #105 of 1841
Any idea about how it stands up to emu 0202? Only the dac section of course.
