Too many issues with those write ups IMO. If anything, the link at HF leaves me with the impression that the dude does not know what he is talking about and with less confidence on the magical properties of WTA.

Noise in most cases is dependent on input signal statistics and solution architecture, proly much more than input signal amplitude. So I have no idea what this WTA does.

It seems the WTA is not half-band filter based. Can't be a sinc either because that is non-apodizing and it seems WTA is apodizing (A sinc sampled at Nyquist and using a rectangular window yields a half-band if I remember correctly). So that leaves us with a lot of random filters.

As far as ASIC vs DSP/FPGA implementations, there are plenty of trade-offs.

It seems that rob watts is designing his filters by hearing with his own ears first over designing based on audio engineering/mathematics/known principles of audio. Don't know if this is best approach but his headfi posts sounds like alot of hyperbole to me, especially on his pulse array topic.

But at the end of the day, the Question to ask is does his dac sound good? I think It's quite a mixed impressions.

Hi guys... and girls! thanks aufmerksam for reminding me about the presence of girls here!  :)p17)

I recently came accross the concero DAC and am trying to dig out information about it...
Apart from burnspbesq/planx have not seen many feedbacks on this DAC... negative or positive.

from what i understood burnspbesq is a real fan of it!  :)p1
Are there other's who have come accross this DAC and if yes what do you guys (and girls) think about it?

There's better for the price now. If you can snag the Concero for $299, but be a good deal. Nothing particularly special.

For $600... do you think you can wait until Q3/Q4? There's a smallish footprint DAC that might be interesting.

If you need transportable, the Geek Out V2 is a great DAC. Since they're being shipped on schedule, I feel pretty confident in the recommendation.

The Infinity is the one that does 2.1V output if you need it as a DAC only. I'm going to use mine with my leckerton.

"smallish footprint DAC"... sounds intriguing... is the one from Schiit ?  :)

Thanks Zerodeefex! based on the feedback am reading it sure seems like a safebet!
I have read more about the GO 450 than the other versions... does it mean that for the v2 it is better to get the v2 with the 450 gain option?
I use mainly my ie800 and mdr ex1000 these days and jh13pro...

Actually the GO100 setting might be perfect for the IE800 and JH13 unless you find those neutral (which they aren't) or too your preference. I think bass synergy might be good with those making the bass response seem a little more linear. EX1000 was just a hair under neutral for me in the low end (like 1-1.5dB) for my tastes, so the 1000 might add a nice little kick to the bottom on those. Note however on the v.1, the 100 sacrifices a touch of dynamic swing while the 1000 adds a little more distortion reducing the ultimate resolution a smidge. The 450 was the sweet spot there (dynamics, resolution, linearity) while the 720 was closer to the 1000 sonically.

I have yet to run the production v.2 through it's paces to fully compare though.

Search the board for "redacted" and look at the California meet thread http://www.changstar.com/index.php/topic,2544.0/topicseen.html.

highly recommended you run these headphone in balanced configuration with GO V2 for a test. And see how you think. ;-)
