The PS Audio and Robertson were bot good units in their day. However, I am willing to bet that the current retail on both units is significantly less than $800 in the Orion Blue Book (which will also tell you the wholesale price your dealer paid for the units). If you like PS Audio, you should be able to pick up a used 5.5 (a much better pre-amp) for about $300. Also, if you check out some auctions, I'm sure you can find a much better and more recent amp for $500 or less. Needless to say, it doesn't sound like much of a "deal" to me.
