HOLO Audio Spring DAC: Affordable discrete R2R Multibit Dac, could be a winner.
This thread makes good reading.... http://www.computeraudiophile.com/f6-dac-digital-analog-conversion/holo-audio-spring-digital-analogu... but nothing about its sound. |
It uses the AK 4137 chip which is third in the "Velvet Sound" line-up of chips from AKM, used also in all Esoteric players and dac's. Interesting that the AK 4137 can be implemented as R2R. http://www.akm.com/akm/en/product/featured/velvetsound/ http://www.akm.com/akm/en/product/datasheet1/?partno=AK4137EQ&link_id=link760 |

Thanks, Greg |
