Don,
I think your posting in this circle is fine. Perhaps, I can create a sub-circle within this circle specific to headphone amps and related gear. I'll look into it today or tomorrow as I have time.
I must buy a new DAC for my TCA HPA-1 anyway, so I'll be chiming in with which DACs have caught my fancy.
Post away....more impressions of the Mytek Liberty are welcomed here.
