Thanks Fran, for putting in the time to review & write up your impressions.
Glad you liked what you hear & yes, as you say there's not a quantum leap in performance between the JKDAC32 & Ciúnas DAC - I'm hoping that's because we are touching on the upper limits of what's achievable with this technology?
Just a note about the battery operation. Although it will work wonderfully solely off the battery, people might think that it is necessary to do so & then feel that plugging in & out the power for battery charging is a hassle too far. All my devices have been designed to be permanently supplied with 5V power while playing & this has no detrimental effect on the sound. This is effectively a battery shunt arrangement where the influence of the PS (noise, ripple, etc) is completely mitigated by the battery connection. Essentially the battery is supplying the power & the 5V PS is supplying a trickle current to top-up the battery. No worry therefore about battery charging.
Maybe, Fran you can comment about this?
BTW, I have just launched my new website https://sites.google.com/site/jkciunas/
I'll be linking my domain name johnkenny.biz to it in time - it currently links to the old website (which has a link to the new)
