I posted this on another thread about tweaking the Buffalo DAC but as Russ from Twisted Pear pointed out it is a departure from the Buffalo so I decided to put it in it's own thread.
I mounted an ES9018 32 bit SABRE DAC on a prototype board as an alternative to NeoY2k or TP boards. Neither board suited my requirements for a number of reasons & anyway I wished to experiment with power supplies, I/V stages, clocks, etc .
The SchmartBoards, on which I mounted the DAC, are designed to allow easy hand soldering of these smd parts LQFP & even BGA chips are catered for. They have solder grooves into which the pins slot & make hand soldering easy. I reckon one could also hand solder these chips on an ordinary protoboard.
Anyway, the costs were a mere $70 (DAC $60 & Board $10) & seems to me like a good bargain and something that can be done straight away without the expenditure or waiting time of other Sabre DAC offerings.
It would be interesting to have a number of people follow the same route & share tweaking experiences.
My first option will be the PS which I plan to run from batteries (4 batteries - DVCC_T; DVCC_B; AVCC_L; AVCC_R) & each 1.2V from an eneloop battery (3 batteries) - no regulators, just caps. I consider the PS to be the most critical part of the implementation of this DAC & running from batteries is a start.
