No! You can't enjoy something other than big systems - we forbid it!
JUST KIDDING!!!
If you enjoy it, man, that's the key. No fault there. It's all good!
New research is showing that I-POD (did I spell that acronym right?) Type aparatus Do "eventuell" cause PERMANENT (as irreparable) ear damage.....
Just don't turn the volume too high on your portable...
It is about expectations. I'm sure if you heard the same level of sound quality coming from a room full of Krell/Wilson (or anything yoou'd care to substitute) you'd probably vomit. If you had the same quality coming from a crystal radio you'd probably think you died and gone to heaven. As for MP3/i-pods, etc. like a cassette, 7" reel, elcassette, 4-track, 8-track, etc. it works in the right place under the right conditions to provide entertainment.
