In most cases, separates are capable of better sound. I never said, A200 DAC Is @gsomin best option given his system. The A200 DAC is not even fully broken-in and you rushed to conclude that A200 is a ‘bottleneck’ in his system. Was that a fair assertion on your part, I let you be the judge of that! This isn’t an argument about separate vs integrated. The best advice for @gsomin is to allow full break-in of A200. Post break-in, if he still don’t find A200 upgrade substantial over Node then going the separates route or another DAC to complement Node 2 or N200 would be the next logical step.
As far as comparison, my last comparison was Aurender A30 vs EMM Labs DA2 and I chose DA2. In this category, I will always choose and recommend separates as it offers most flexibility and convenience to tweak the sound to your liking.
