That is very good to hear, I'm tempted to give the uDAC-2 a try

Do you think that the udac-2 will have the proper power for the akg 702? Or should I forget it and look for something better?

hell no, usb powered lol

HA, can you shed some lights on uDac-2 w/ LCD-2?

 

Thanks!

I have already, somewhere In either the uDAC-2 or LCD-2 thread. I'll have to look for the link. In a nutshell they sound good together. With DACport the HE-5 LE become the better combo, but with uDAC-2 I prefer the LCD-2.

I get hissing on my IE8s with udac2, any fixes?

post #157 of 872
I tried my LCD-2 w/ uDac-2 today. So far so good. Volume wise it can go very loud, much much louder than LCD-2 out of my iPhone 4. Sound quality wise it adds more brightness to the sound than my receiver or iPhone 4 and I like it that way.

No hiss too.

I got the uDAC 2 today and first impressions are the following:

 

Very small, very well-built unit (Good Job Nuforce).

 

Asus 1000H (Laptop) - (J. River Media Center playing flac files) - > USB - > uDAC 2 - > DBA-02.

 

There is a "mechanical sound"  when the unit is turned on, like a frequency which "goes" higher the higher the volume (notice that it doesn't get louder). I have not a digital out device to try that out.

 

The noise is not noticable at ~ 9 o'clock. But I would like to get quieter than that.

 

I don't know what it is but it's driving me crazy. Any suggestions? Something I'm missing?

The Udac-2 as a dac (rca out), I believe you said comes pretty close to the Pico dac, almost indistinguishable.  How does the amp in the Udac-2 compare to let's say the Pico amp or RSA Predator, or other portable amps?

 

Thanks

With my IEM I'd say the amp section is very competitive with the top tier portable amps, and only very slightly below in micro-detail and soundstage. It varies a little more with different full-size phones, depending on power requirements of the phones.

Thank you.

Larry,

 

Thanks for the great review and follow-up posts.  I am doing a bit of system rearranging, and now find myself looking for a DAC to do triple duty.  The wife and I are setting up an office in a spare bedroom, and I thought that a desktop system with very small speakers and a headphone jack would be nice for my HD-600's or Ety ER-4's.  One option may involve moving a tube headphone amp/preamp into the office.  But, I may just take the plunge into PC audio and use a DAC with my laptop or netbook to keep it simple.  The third use for the DAC would be to hook my computer up to my main system when I am in the living room.  I initially started looking at DACs up to $500, but that led to $600 and then $1,000.  I could spend this much, but as this is my first DAC and I am just getting my feet wet with PC audio, I thought the uDAC-2 might allow me to see how much I will actually use my PC as a source at a reasonably affordable price.  But, I have two concerns.  Can the uDAC-2 drive the HD-600's, and is it up to the task of feeding a two channel system with a tube preamp and a solid state amp?  I know the latter questions will depend on the computer and the source files, but am I asking too much from an affordable DAC?  Also, I was concerned about having the volume pot in the path of the RCA outs when feeding my preamp, but it appears that any DAC with a true line out is gong to be much more expensive.  Any thoughts?

On your second point, yes, it will certainly be good enough to let you explore PC audio.  If you have refined ears and like using your PC this way, you'll  probably want something better eventually, but it will be a perfectly adequate testing-the-waters device (more than adequate, actually).  Turn the uDAC volume control all the way up to minimize its impact on SQ and control the volume with your system.

But, I have two concerns.  

 

(1a) Can the uDAC-2 drive the HD-600's, and (1b) is it up to the task of feeding a two channel system with a tube preamp and a solid state amp?  I know the latter questions will depend on the computer and the source files, but am I asking too much from an affordable DAC?  

 

(2) Also, I was concerned about having the volume pot in the path of the RCA outs when feeding my preamp, but it appears that any DAC with a true line out is gong to be much more expensive.  Any thoughts?

(1a) The uDAC-2 can drive the HD600 to decent levels and sound good, but a desktop amp will bring them closer to their full potential.  If you like to play very loud, you'll want something more powerful to feed the uDAC-2 into.  

 

(1b) It does a nice job feeding a larger amp like my Woo WA6 or eXStatA from the RCA out, and should do well with your two channel rig mentioned above.  The RCA out seems to keep up just fine with my other $200-400 mid-fi DAC's like iBasso D4/D10, HR Micro DAC and Pico DAC-only.  The uDAC-2 is more detailed and spacious than any of my DAC's using the PCM2702E Japan or lesser chips.  Plus, if you have a nicer DAC that doesn't do USB, like in a home theater receiver, it does a nice job of supplying S/PDIF coax digital into your HTR from your computer.

 

(2) Even if the volume control was holding the uDAC-2 back, it still somehow keeps up with the other more costly DACs above that don't have variable line-out.  In the $50-$150 price range you could get a hotaudio or Headstage USB DAC with no volume control, but I haven't heard them and can't compare.  The Super Pro DAC707 via optical and with an upgraded PSU is at least as good as the uDAC-2, but the USB performance is not quite as good as via optical, and with the stock PSU it's still at a similar price as uDAC-2.  There are many other DAC's in that price range you could consider, I just haven't tried many of them.
