Nick the Slick's Simply Efficient Room

No line input since all I'm dealing with is the integrated sound card on my motherboard, so I'm stuck with the mic in. I'll try to take another measurement with the mic boost defeated (have been measuring with +10dB) and set my graphs up according to that link.

Question about the mic input though. Could that be old information? Does it only apply to low end stuff or does it apply to all mic inputs in general? I ask this because maybe this just refers to cheap inputs found on laptops and such, just wondering if me having a mid/high end motherboard (well, mid/high end in it's time) made any difference? Could it also be because the writer of that post was using SPL meters which only have line level outputs (unlike the audyssey mic I'm using which has a regular 3.5mm jack)? I'm just wondering why it makes such a big difference (I know you said because of noise, but like I asked, could a higher end sound card/input make that point moot?)
