Perhaps an outboard stereo amp with excellent specs for accuracy and a headphone connection, that doesn't have to be high-powered or have bells-and-whistles, connected to the outputs of the 950 for used recording or a second zone.

I use a Headroom Little headphone amplifier plugged into the 950's tape output. I have two sets of headphones, a pair of Sennheiser HD 600's and a pair of Grado SR 80's. Headroom's web address is: http://headroom.headphone.com/. The current price for the Headroom Little is $259.00. The Headroom Little is a good sounding headphone amp and is very upgradeable.
