Originally posted by KikeG However, reasonable quality internal cards (Turtle Beach Santa Cruz and better) don't need to have an external DAC to perform well over this EMI noise issue.
Originally posted by JonPike I was wondering though.. you guys reccomend them, but can you still buy them? Creative hasn't made the 64/128 for 3-4 years haven't they? Can these things only be found in swapmeet bins if you are lucky? I haven't seen one in a few years, and I go to a lot of computer swaps..Not quite what I'd want to hear if I was looking to get a card..
Originally posted by ben Yeah, there are MANY versions of the PCI 128. The earliest generation had a line-out, line-in, and mic-in. I think that was the Ensoniq 1370. Other generations had exactly the same board layout except there was another output. I *think* this was the 1371. Several versions followed this, don't know if they used Ensoniq chips or not.
Originally posted by Randum Really? How do they manage that? Shield the DAC chip on the board?
Even so, wouldn't EMI still affect the signal coming off the (analog) cable coming out of it? Sure, its not actually inside the case, but very near it, as opposed to an external DAC, where the signal doesn't 'turn analog' till its a good distance away from the case.
I don't know, Ive actually never owned a good quality sound board like the ones you recommend, so I don't know how it compares subjectively, but it seems to me like it would always be worse (on the emi issue anyway) than an external dac.
