What could prompt such a rash query? Well the products from iFI actually. I have the micro phono stage - it is great, in fact so good I wanted their DAC to go with my CD transport. But oh no, as I understand it their DAC is for HD downloads and not for CD at all, something to number of bits per second or some such. Now I love the sound of my vinyl playback and in fairness it has had a considerable amount of more investment than my CD source system. So the query I have is, if I was to invest to to an equivalent level for my CD playback would it match my vinyl system, or is the format limited and now surpassed by HD downloads?
