most euphonic DACs?

Good one.

Don't know any of the DAC's you mention but I have heard quite a few DAC's in my time and the most euphonic by a long way to my ears is a Killer DAC. It not what you would call coloured but has this full rich sound that is very addictive.

Thanks

FORSELL air reference dac (n tube,but lush ???), CAL alpha ad JADIS JS1 come to mind

The Monarchy M24 is a good one.

The Zanden DAC. Euphonic in the best possible sense.

Mhdt Havana, Havana Balanced or Stockholm v2 DACs. These are all Non-OS DACs with tube buffer outputs. Highly tunable via tubes, capacitors & ability to use either the stock PCM56P or the AD1865 chipsets. They can be voiced to sound euphonic but it's more a matter of sounding authentic, musically-convincing, having rich tone and being non-fatiguing to listen to.
