Haha a Brit thing.

 

Let's face it, designed in the USA, made in the UK, USA or Switzerland., very extensive experimentation + documented specs.  Using one of the worlds best DAC chips.

 

...come on China, where you at?

 

 

Edit:  and since I already own a very similar DIY design of the ESS ES9023 (I'd venture the most similar design there is), I can vouch for how good it sounds connected to my stereo.

 

I wrote last year, DAC's do not "sound the same", I could hear the difference between this and my internal RealTek sound-card... next door.

Voldemort didn't design the stencilling on thee front of Oliver (or Justin's) amps - that is most definitely a British thing.

All the O2 + ODAC combos still use the portable O2 and not the desktop ODA right?

Correct, the ODA won't be out until late summer. The O2 is apparently being modified, however.

Did anyone got to test this DAC? I mean with the O2.

So how did you find the synergy between them (with O2)?

Using the same or very similar parts does not guarantee similar performance, the quality of the implementation is important.

I'm more curious to see how it compares with other diy DACs. I have a gamma2 I'd like to compare with it.

 

I (finally) finished my O2 amp today, and I'm impressed. I've never owned a solid state amp before, but it does what I hoped perfectly. I hope the dac delivers in the same realm. I think it will.

Apparently a part related to the power of the power adapter plug is no longer being made, so NwAvGuy is changing the O2 a bit. I tried contacting him about it, but haven't heard back yet.

Sorry, don't know how much he's changing, it may be that one part, or it may be more.

I think it was something to do with how the amp acted when the battery was low.

Seems that it will be released: http://www.diyaudio.com/forums/head-n-hifi-walter/211583-odac-general-technical-discussions.html#3

Thanks Taowolf51. I'll look forward to more info on his next blog update. Doesn't sound like it'll be a sound quality improvement modification, pity.
