Brief Odac impressions - Page 84

The O2 can run off of just batteries, but they have to be charged so you will need an AC to AC adapter.

Unless you want to take the batteries out and charge then externally...a real pain.

The ODAC is powered from the USB buss power in a pc.

The way you wrote that makes it seem like the ODAC has batteries, which it doesn't 

Oh and an update to my situation. I've solved the clicking problem altogether i think. I changed the colour quality to Medium (16 bit) rather than the default High (32 bit) in ATI Control Center. Of course the display isn't as good as before, gradients aren't smooth any more, Windows aero is disabled, but I can live with this.

Sorry for taking up so much of the discussion this past couple of days. Hopefully this may be of some help to newcomers with similar problems. Now back to music listening!

But yes with a PC if you get the O2 with a battery. 

 

I would not do it with a laptop because of the ****ty power supply.

1) some phones can power the odac

2) laptops almost always have cleaner power than desktops

So if that is the case, I won't need the seperate power adaptor?

You still need one to charge the O2.

The O2 runs off batteries*

Thanks

The Standalone ODAC is powered by USB.

The Standalone O2 can by powered by two, 9V, rechargeable batteries or a separate A/C transformer.

The O2+ODAC Combo requires a separate A/C transformer.

1) yes but not well (100mA limit on mobile devices. ODAC requires 125mA)

2) Beg to differ, laptops have such varying quality in the USB ports its disgusting, ASUS and HP seem to be fine, but especially older laptops or cheaper ones really do such. PC's are not immune, but are a lot less effected.

thanks for that....i edited my post..meant to say O2 can run off just batteries....

The ODAC requiring 125 ma....USB 2.0 Spec is 500ma total avail, if implemented to spec.

I actually measured the current draw and it was only 50ma...

Take a read here at Texas Instruments: http://www.ti.com/lit/an/slyt118/slyt118.pdf

1) what adydula says

2) Laptops have better cleaner power going into them.. Not necessarily coming out of them. That's all up to the implementation :)

*sigh* 

Measure it if you don't believe me guys. I know the burden of proof is on me, but, I really don't care what you guys believe. Also, I could very well be mistaken.. You know what, that would be easiest for everyone. I'm wrong, desktop PSU's provide cleaner power. I take back what I said.

To SupR-Pinou:

Thanks a lot.

After a few days with my ODAC + o2 I think i'm ready to post.

The very first time I listened I thought I knew what everybody was talking about with this 'Crazy Treble' (I was using K702's) and the treble seemed harsh and very in my face, I then changed USB ports and it sounded fine,although I then put it back into the same USB port as the first time and it again, sounded fine, which confused me a bit. 

I discovered that the problem was merely my ears/brain.  I first of all hadn't listened to my K702's for a while and secondly had the volume much louder than I usually listen thus giving me this completely different representation of the DAC with super loud treble, although after some listening of familiar tracks I am very very pleased with this DAC.

It really is super-clear, I am re-discovering further elements in tracks that I couldn't quite pick out before (was previously using the headphone out on my Native Instruments Komplete Audio 6 into the o2 Amp) and the instrument seperation is even better than before.

For the money I really couldn't be happier with this DAC, does exactly what it's supposed to, faithfully convert a digital signal into an analog one.

I'm yet to try it with my monitor speakers but if I do soon I'll post it here.

P.S this may be a bit off topic, but when I'm using ableton live with my NI komplete audio 6 it lets me use it under an ASIO driver so it has very low latency, but when I use the ODAC I have to use it as MME/DIRECT X driver type giving annoying latency, anybody know how to fix?

I'm finding the ODAC a very intriguing little device, but I have some questions. I've done some searching and reading (although I only read about the first 20 pages of this thread, so if the answer is there, I apologize), but I haven't found the answers.

Is the ODAC asynchronous?

I've read that it out performs the hrt msii and some people say it even is better than the msii +, but has anyone compared it to the hrt headstreamer?

Has anyone read how this compares to the Musiland Monitor 02/Dragon US?

I have the Headstreamer and am looking for an upgrade, but wouldn't want to spend the money on the dac and an amp if the audible sq gain is only minimal.

I'm using woody Grado 225i.

Thanks

Matt
