I've had 2 pairs of Logitech PC speakers (both with Dell branding and a sub) and both sounded fabulous.
"...and found myself singing along as the music plays! No longer do I criticize how the music sounds on the system. I am not listening to audio equipment anymore. I’m simply hearing my music and enjoying it. I am now doing what 95% plus of the population does with music…they consume it as a form of entertainment."
You've raised an important point here.
On my desktop system, playing mostly 320kbps MP3 files, I have rarely been troubled with any thoughts of criticism for the sound.
When I switch to my main system I'm immediately aware of sound quality issues.
Every single time.
Sometimes I can bask in the increased dynamics, bandwidth, imagery and separation but other times I'm finding it difficult to escape the blatantly obvious fact that some recordings are not very good.
These issues don't happen with the desktop system because it is far less ambitious and far less revealing.
The Logitech system doesn't pretend to sound life-like but everything upwards from 128kbps MP3 on it sounds good.
Perhaps the real problem with high performance systems is that they're just too revealing for the majority of recordings out there?
A bit like studying some of the old classic paintings with a magnifying glass?
