It doesnt bother me if the audio is perfect or not.
Most people do not realize that the speakers/headphones they use are still one of the most important, if not THE most important, aspect of a sound setup. You can have a $5000 audio card but paired with a 2.0/2.1 sound system you bought 10 years ago at a garage sale just wont cut it. Heck, I still use a set of Altec Lansing ADA-305 speakers I got YEARS ago.
I would love to see something of a combination package with an audio card/chip and a set of speakers/headphones that are actually paired to work and sound the best with said card/chip. Dont throw out a high end sound card/chip and then let the user decide on speakers/headphones as 9 out of 10 times they will go cheap and screw the whole experience up and in turn, give bad ratings for something that is entirely their fault.
so for your numbers (numbers are so 1980's. It is hard to put a number to something when that number depends on other aspects, like speakers)
There are the pretty numbers for you
