Many audio tests will only concentrate on this area only.
Soundcards usually have filtering sections to remove unwanted signals and only certain parts of the circuit are suceptible to any interference that can be of a issue to playback. Some blow the entire subject of EMI/RFI right out of proportion. If it is a concern for you buy a sheilded card or shiled the one you have.
You are correct in that some get way to anal about the entire subject and worse many use their current audio gear or knowledge to make up for other shortcomings in their personality. People that are rude and jump on others who are just learning. You can know more then another and offer your advice and opinion without turning it into a *issing contest. You will find alot of that going on in the larger "dedicated" audio forums.
I have a background in Electronic engineering and I add a little bit of info to my reviews about electronics as I figure this helps people learn about what makes these cards function so they can make informed decisions based on reading specs and other information. Although I try not to get too complicated just enough to convey the point. Hope this Helps.
Those forums are indeed full of posts that are wastes of bandwidth (they seemed almost inevitable in discussions about cables). I quickly learned to just avoid threads that had decayed to that point. That aside, what I've managed to glean from discussions on the subject is that when you try to "block" HF noise that is already in the circuitry, then that noise may modulate itself down to an audio frequency if it is not damped somehow.

Without getting to indepth and going way off topic; that is sort of on the topic of Harmonic distortion, where certain frequencies can affect others. Forums are great if you can extract the useful from the useless information.

I should have realized that intermodulated noise would just show up on a THD plot anyways.

experts in a fields have built distinctions that require some training/practice to get to the full experience.
I enjoy coffe, even if I cant give every nuance of what a coffe tastes like as someoneone who are testing it for the producer.

I will enjoy my essence stx when it comes since I to some degree can hear the differences.
I just hope I dont need to get new recordings of my music ;)

The only time you might need new music is if your using low bitrate or poorly encoded MP3. I moved away from that years ago. FLAC and high VBR are the only files I bother with and I am slowly moving totally to FLAC. NO that the FLAC file format is improtant rather, the Lossless file is what I am after.

A posted on Head-fi has stated that right out of the Box, the Essence cards heapdhone amplifier sounds better to him then his $400 dedicated Can ampliifer.
I mention right out of the box, as the card will also get better over time the filters will "burn-in" providing improved soudn quality.
More impressions to follow.
