Loren, if you are a music guy and SQ for movies is a seondary concern, in my opinion getting the best SSP you can afford is not the best way to spend your money. You are better of with a two box approach.
So first you get a very competent SSP in the 2K pricerange (Marantz, Onkyo) for multi channel duties. You could even keeep the Sunfire for a while. Then, you get a very good 2 channel DAC with volume control and analog input(s). You use the analog input on the DAC as a HT bypass for your SSP. You run the Oppo 95 digital into the DAC for 2 channel. Depending on how much you want to spend you can get the Wyred4Sound, the Bel Canto 3.5, the Zodiac Antilope Gold, Aesthetix or any of a bunch of others very good DACs with volume control and additional inputs that are now hitting the market. This approach will give you MUCH more bang for the 2 channel buck than going the SSP upgrade route. On two channel, a top notch DAC/Preamp will trounce the Integra and the Classe for that matter. Additional advantage is most of said DACs will have an asynchronous USB input.
