Thanks again for keeping this a lively discussion, guys, and I'm sorry if I came off as oversensitive about my system. It's just that up to this point, the differences I've heard when comparing digital sources and cables have been noticeable, but not amazing improvements. So, it's sometimes hard to imagine that upgrades to this end of the system will result in huge positive changes (but I AM trying to keep an open mind about this).
I keep coming back to the question of why does it seem so hard to get my system to sound good with a wider range of recordings? I've read posts over at the Asylum where guys claim this never happens to them and that their better gear makes all of their recordings sound better. To be honest, I find this a bit hard to believe, as it is so contrary to my own experiences.
I can think of many CDs that I own (Beatles, Frank Zappa, Todd Rundgren, old Ella Fiztgerald or Billie Holiday recordings, to name just a few) that are not soncially perfect but are musically wonderful. Now, these CDs sound great in my mediocre car stereo, but pretty awful under the "aural microscope" of my home system. Does this mean we can conclude that my car stereo is better than my home system?
And if it's all about digital sources and my cables, why is it that I when I listen to my Sennheiser HD-600s using the same CD player and cables I don't have the same problem? Certainly, the headphones are very revealing of bad recordings, but 99% of the time I still find myself able to enjoy the music without being completely distracted by the imperfections in the sound.
Doesn't this bring us back to speakers and room interactions as the likely culprits?
Finally, a note to Rocket: what the heck is the doonah test?
