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.

Good review of the sound got with this dac in just 2 paragraphs.
I take it with PCM, 16/44 or 24/96 or DXD?.
Later one doing DSD would be nice as well if you have any?

Cheers George   
Thanks George,
PCM 16/44, I have tried upsampling via HQplayer to both 352.8 pcm with very good results. My current computer is just not powerful enough to do high res Dsd. 

I must add add to my thoughts above that I am feeding the DAC with a uRendu via USB. I will be adding a Singxer Su-1 just to see what it will add via i2s 

Cheers

Have you tried DSD64 and -2 poly filters?  I am fairly sure if your pc can handle upsampling to 352 you can do at least DSD64.
