Rob,
I am running a NAD S100 Pre and a NAD S200 Amp with PSB Goldi speakers and they sound wonderful. A really nice combination. These are the Silver Series NAD units which are several levels above your average grey NAD stuff. In my experience many audiophiles ignor these NAD Silvers, that is until they are heard. They really sing with the Goldi speakers. I have a large room and also play it loud. The NAD S200 has plenty of meat to drive the 4 ohm Goldi's. Good luck
