Headphone System, a Headphone/Desktop System by smk

System Overview
Build a system for evening/night listening using a dedicated server in a limited area.
Music Preferences
Nearly anything well recorded but primarily acoustic, female vocal & jazz.
Listening Impressions
Sounds good with Passive VLC.
Other Comments
Prefer simple/straight-forward to complex/high-maintenance. I still think the best sonic tweaks are ear-wax remover & late night listening with eyes closed. The highest complement I can give my headphone system is I never get tired listening. Tubes take the edge off. Headphones may not be the last word with artusts/performers inside your head but are better than doing without. Best of all, I can listen during evening/night at realistic volumes without disturbing neighbors. My system is complete unless a component fails & when it does I will replace/repair.
