Nice list of DAC options, so far. Please let me add this one.
I’m having very good success pairing an Ayre QB-9 TWENTY with my Persona 3F’s. The Persona’s holistic imaging and full range, broad off-axis response is well supported.
The TWENTY upgrade is essentially a new board with most of Ayre’s latest DAC technology. I’m running Cardas Clear and Cerious loom in fully balanced mode, but frankly with its built-in power filters and FPGA schemes, the DAC seems less dependent upon higher end connections.
