Great questions and suggestions. Thank You for that.
As far as improvements are concerned - Oppo is a jack of all. So I am expecting more resolution from a dedicated DAC.
FGPA DACs - I have been eyeing used Hugo TT2 for sometime now.
About the Bryston - heard mixed reviews - but intrigued by AKM chip, though I know that it is the implementation that matters.
Weiss converts everything to 195 PCM and that is not the path I want to go. Will kindly request posters to not bring up PCM Vs DSD discussion here.
Wandla - was not aware of this. So will surely look into this one.
One more DAC that I am eyeing is the Okto DAC. This is one that has high recommendation from both camps.
