Review: JDS Labs O2 (Black edition) + O2/ODAC discussion - Page 29

post #421 of 498

I think what I'm most concerned about, now that it has been verified that the O2 is pretty much neutral (this claim has been reaffirmed by many sources, including you-know-who), is that I have an equally neutral DAC, and I am hoping the ODAC is equally neutral. If it isn't then I will get the O2 but with a different DAC. 

 

Is the ODAC neutral? Or where should I look?

Yes definitely! No audible colorations to any of my headphones at all.

It's comparable to the Schiit Modi.

 

ODAC doesn't sound bright/warm/cold etc. Well for that it depends only on the recording but it's not coming from the DAC.

Whats not perfect about it?

Usually not a problem but as already mentioned:

- some IEMs can have audible (barely, a few tenths of a dB) FR variations even with the low output impedance of the O2
- channel imbalance at low volume with very sensitive headphones/IEMs - this is perhaps the most common problem
- clipping in the gain stage can be an issue sometimes, depending on the source output voltage and the available gain settings; this can, however, be worked around by reducing the volume at the source

That was probably what "this guy" was trying to demonstrate with the ODAC, that a good implementation is not necessarily expensive.

Yeah, I checked out the Modi on behalf of your suggestion. :) I think I still want to go with the ODAC, and I am taking into account your claim that it's a neutral DAC. I will be further researching this. :)

Agree there.....no real need to spend mega-bucks there.....

 

as an aside I noticed JDS is selling a O2 kit!!!

O2 kits have been up for a while. We recently updated the photo:

Yeap! And there you have my kit assembled! 

 

 

post #429 of 498

With the cans I use there is never a clipping issue at the levels I listen to....I dont want to loose any of my hearing capabilities!!

 

IEM's arent in my world...so no worry there...

 

HE6 not going there as well....so for me

 

the O2 is "perfect"......

For my application is kind of perfect as well. Pretty happy with the combo. smily_headphones1.gif

Do you have any idea o2 with lipo batteries in higher voltages from the normal batteries? Or what do you think the best battery for o2? smily_headphones1.gif

Voltage in O2 is internally limited to +/-12VDC. It's only safe to use NiMH types, and NwAvGuy's recommendation to use a Low Self-Discharge NiMH remains best. Tenergy is the most popular brand.
