Mainly looking for simple suggestions for my home rig. Final cost being $800 or less. Currently in consideration are the following: --KOSS ESP/950 --Fostex TH600 --HiFiMAN HE-500 --Sennheiser HD600 I also have the opportunity to get a Sansui SS-100 if someone will vouch that it's worth it. Anything up to $800 is a worthwhile suggestion. Thanks. Only looking for headphones at this point.
