and is typical of pop/rock music these days. There is also no digital distortion apparent over my monitors/stereo/headphones/car or in the waveform either.
You might want to do a little more comparitive listening on your monitors/headphones. If you can't hear the distinct distortion artifacts at :10, :41-:45, :55-59, 1:26-1:30. Since this is an effect of probably limiting with too short of a release time, it is indeed considered "digital distortion". Something I dont' hear in big time masters, even when under heavy limiting.
I will not rule out that the tracks themselves could have the distortion on them. Depending upon the A/D you used, the dithering while recording could be that godaweful!
If this the effect of mp3 encoding (unlikely because I never hear that when I encode using Fraunhofer codecs at 192kbs), then you really don't have any business posting something that claims to be "mastered" as well as the big boys using a low bitrate and crappy encoder. I would be interested in hearing a .wav file of the same mix to really tell, but I mostly sure that this is the result of a cheap "mastering" plugin being taken far beyond what it is actually capable of doing without these kinds of artifacts appearing on the master.
Again, if you can't hear these distortion artifacts on your system, possibly, your system lies to you! My Lynx converters DON'T lie to me as they have an extremely high amount of headroom. If anything, stuff that doesn't distort on my Lynx D/A's will often distort on lesser converters that lack the same high headroom and accuracy, such as the Delta 1010 converters. So, if I am hearing distortion on these converters, well, it is definately there.
Your master also lacks true sub harmonic content that would give it "size". Possibly, you used a high pass filter set too high. It is very easy to want to remove those sub frequencies in the pursuit of a hotter master, because those low freq's eat up a lot of headroom in the mix, and cause limiters to limit a lot. You might have been better served with a low shelf filter set at about 60Hz and turned down maybe 3-4db. This would at least RETAIN the subharmonic content, just at a lower volume overall.
I have some mixes here that I would gladly send you to "master", and we can compare your job against what a $100 an hour mastering studio did with them. I can assure you that you will not get close, because I tried like hell to get close and couldn't using plugin's. I have "mastered" a few CD's in my time too.
This is silly conversation. If you need to make your mixes a little louder and do some gentle eq correction, by all means, go at it with plugin's! If retaining as much of the accuracy that the original mix had, but with some well done compression and limiting and useful eq correction is what you are after for a release, working with a competent mastering engineer is what you need.
Is there "secrets" to mastering effectively? Indeed there are! Are they easy to explain? Hell NO!!!! Does one applied solution work for the next client usually? Almost never. Is there "a place to start"? Yes, by LISTENING. LISTEN on something like Meyer HD1's and you will hear audio in a totally different way.

LISTEN with top of the line, well clocked D/A's. LISTEN in a room that is acoustically nuetral. APPLY subtle corrections.
Can all mixes be mastered on an even level? Hell NO!!! The less a ME has to do to a mix, the better off the master will be! Bob Ludwig talks all the time about what he DOESN'T do to mixes that he masters!
Anyway.........
