HOLO Audio Spring DAC: Affordable discrete R2R Multibit Dac, could be a winner.


Many manufacturers are going back to R2R Multibit d/a conversion, a good portion of audiophiles are saying it sounds better than the cheaper d/a conversion of Delta Sigma, (1 bit), Bitstream, Saber. etc.
And it says it uses dual R2R’s Multibits to support DSD natively!!? 

Product Description:This new DAC.”Spring” is the first design of a new era, a milestone for HOLO Audio’s own Jeff Zhu. It’s a full discrete R2R type of audio decoder and does not have off the shelf-DAC chip! This is a bespoke custom-designed core DAC module and truly a breakthrough with technology for any DAC chip today. The Spring is here to achieve new heights, new dynamics and simply a full spectrum of audio to please the aural senses. This Dac has been called the poor mans Total Dac / MSB / Wavedream / Chord Dave Etc. It plays with the big boys.

The Schiit Yaggs is much more technically advanced in its actual 21 net bits... patented AD -Bruz technology
Huh? Not sure where you're getting 21 net bits from since the Analog Devices AD5791BRUZ DAC they use is a precision 20 bit DAC. Feed it 24 bits of data and the last four are rounded off. If anything, the Spring DAC is closer to 21 bit, given their claimed SNR of 126 dB. I also think you're confusing Schiit's oversampling digital filter (which is proprietary, not patented) with the DAC chip itself. 
I see - dual differential. Still, I don't think it makes much sense to claim that. The input register doesn't even accept more than 20 bits for data. But what do I know? I'm just a regular schmoe... And not that it matters all that much anyway since we're talking about deafness at this amount of dynamic range.
