I will reinterpret for Frank in the language of earthlings: Digital is not perfect, but it needs no excusing. These days, a cheap DAC with an op amp output stage, well done, is significantly cleaner than vinyl, and in your analog systems, it reveals distortion that your ears don't like it. It's not the fairy dust distortion Frank sorts out with Harry Potter's soldering iron. It is boring, common stuff: Amps struggling to drive speakers that are a bit too much for them in difficult transients in the higher frequencies, passive crossovers, too many noise-making parts in too many boxes, strung together by far too much noise-making wire. Accumulative noise pushed through a system by an unforgiving source = harsh upper mids/trebles.
But keep it very simple and very clean, hook even a cheap but modern, competent digital source up to more amplifier than it will ever need (my small monitors have 325 watts per channel). Now drive a pair of full-range drivers, or a very good pair of headphones, or a well-designed active speaker system and that upper-midrange glare, harshness, "too bright" etc, disappears. It's gone. No excuses. The problem is that "very simple and very clean" describes very few audiophile systems. Perhaps those stacks of boxes with their redundant power supplies, resistors, capacitors, internal wires and and external cables, feeding not quite enough power to huge speakers containing another nest of resistors, capacitors and wires was what's best for analog. It is dead wrong for digital.
