Stand alone dac vs built in dac what's the better

There are severe jitter issues with external dacs...which manufacturers have the upper hand controlling when designing their own players...but the future is pc/media based...where internal dacs and resolution...unlike cd...are actually improving at warp speed

Manufacturers and dealers are the ones touting improvements...and even they concede its marginal at best even on the hi end as they have upsampled,oversampled,etc for years...but everyone wants to justify their purchase...even where so called improvements are incremental...last time I checked cd was still 16/44...

Very open ended question...guess it really dependppos on the initial quality and age of your equipment...an older cd player, especially an entry or midfi
one...could possibly benefit from an external dac...however...in my experience...the additional cost of a dac and cables didnt justify the cost...at least in a cd based system...in which technology hit a ceiling years ago...so the real future is hi rez downloads...pc media...where a hi quality dac might be beneficial
