Is this a return to vinyl or a new experience for you? I've never owned a 950 but would agree with Gonk that bypass is probably the best way to listen to LPs. If the 950's analog bypass works like the 990's you will get a summed left and right bass fed to the subwoofer so you may want to lower your sub's level.

I returned to vinyl about a year ago when I bought a vintage Pioneer TT originally sold in 1978. I've added a new Ortofon cartridge and it sounds pretty sweet. I must admit I had to get reacquainted with all the mechanics and variability of turntables and it can take some time to get at TT dialed in. vinylengine is a good resource for TT info. Enjoy working out the kinks in your turntable!
