I recently acquired a Bryston SP -1 for $450 to use as a two channel pre-amp using a Benchmark-1 USB DAC that I got for $400, with an NAD T744 as a two channel amp. It sounds pretty awesome going into a pair of Klipsch Cornwall lll's. It sounds better than an Integrated Amp that you cn buy today for about $8500 at Audio Advisor . I owned that amp.Thought I should share this.
