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.

Thanks charles review,  as i said before holo spring sound really good and close to my ex metrum panave performance, but after i replace the ddc from bryston buc-1 to singxer su-1 via i2s hdmi, it make a huge improvement, more detail and better 3d soundstage, more silent background and also sound more clear than using Aes in , i feel this combo ready to outperform metrum, i am using aurender n100 for source, vitus ss010 and volent vl-3 as amp,speaker

Many thanks,  Charles, for the update.
I have auditioned the Bricasti in my home system and going by your description of the Holo's sound next to the Bricasti's, this is high praise indeed.

Thanks guys,
My post was no attempt to write a  formal review but rather an impression of its performance relative to a know highly regarded reference such as the Bricasti SE.  If the additionof the Singxer SU-1 provides even modest improvement then we have a DAC of enormous performance/cost  value. This is excellent news for those shopping for terrific sound quality at very reasonable cost.

charles1dad, it is always a good thing to post "as you hear it". There will always be skeptics. I could clearly hear "changes" with power cords. So one can understand why a fuse change might affect.
Anyways, I am now interested in 2 DACs - The Kitsune Spring Level 3 and the Bryston BDA-3. The advantage I see for Bryston is the DSD over HDMI. If there is a simple way to route a DSD to the Kitsune over IS2 via a HDMI cable, I am all ears.
