It's only a matter of time before someone comes along and vehemently asserts, ad nauseum, that there's no difference in sound quality between "properly implemented" DACs.
PLEASE do not listen to this. Instead, listen to as many DACs as you can and decide for yourself.
There will be some instances where the differences between any two given DACs will be minimal. However, there will be other cases where differences may astound you. It's only through listening that you'll learn what YOU like.
Listening in your room, in your system, is best. There are various online sellers who offer trial periods with return/refund policies.
