Are any of the newer DACs better than BB PCM63s?

Best dac chips made period.Followed by the 1702k BBs

Implementation fo course is very important,and actualy is the key to how well a DAC will untimately sound.I respectively disagree that the Crystal chips come any where close to what a 63k,or 1702k dac chip in cleanliness,and overall musicality .From talking to a highly repectited tech who is in the Arospace industry there are very few if any chips made today for the consumer that come close to the performance of those mentioned above.Another important factor is the power supply.As more and more of these are now made overseas,and the quality of most of them is questionable, also has a large bearing on the performance.This is why you see a glut of modders comming out of the wood work,taking stock pieces and bringing them to a more satisfying level.

Quite simply noise is the biggest culprit in Audio particuraly digital.This is why a good many audiophiles still swear by vinyl even with all the clicks and pops.Most digital just does not sound musical,nor do any of the Hi rez formats other than some very few true DSD transfers.You are seing more and more maunfatcurers claiming to use military spec parts in their gear,and though the cost can be prohoibitve in some cases,there is plenty the the consumer maufacturers could use that is very inexpensive that is military grade and would imnprove gear by leaps and bounds ,but unfortunatly they are all ruled by the profit margin and very little money for R and D which is always the achiles heal in audio.
