 		 #180002 - Yes, but it's not cheap
Responding to: ???'s previous message
Some PC sound boards offer 24-bit resolution. I've never taken a close look at them, but, quite frankly, I find it amazing that they can make that claim in a PC environment, with all the switching noise, etc. that they contain. I've seen a couple of those 24-bit resolution sound boards, and it's clear that they take great pains, using precise passives and careful grounding and bypass strategies. I'm still amazed that they get by with the claim that they offer 24-bit resolution. I'm forced to wonder how much of that resolution is actually brought to bear on behalf of the end-user, though. Even if it's only 16 bits, it's pretty amazing.
