OK, gave them a run.
I don't remember which is which, and i didn't visit Soundcloud to remind myself yet because i wanted to try and give as objective an opinion as possible. I do remember i liked the Profiler's S/Pdif least, and that it was the last clip of the bunch.
First clip sounds worst now. Not bad, but slightly harsher and more dithered, maybe? Sounds like more background stuff and less 'body'.
Second clip is way smoother. Perhaps a tad too smooth.
Third and fourth are very close, but i'll take the fourth as my favorite. Very 'meaty' sounding midrange and the transients sound just a tad smeared, making them sound 'bigger'.
The Profiler's S/Pdif sounds better than on Soundcloud. It's actually very close to the third and fourth clip, but the transients sound slightly quieter and shorter.
It might be great with other sounds, but this is so over-gained it needs some help with note separation.
To Sambrox:
They are damn close, i agree.
The thing is, it's not that my monitors are that good, it's that i know them so well. I've been mixing on them and listening to my music almost solely on them for the past, what, six? seven years now?
I am also hyper-sensitive to high frequencies, but i don't think that has as much bearing.
I'm not sure i could tell the difference on a pair of speakers i didn't know as well.
