I wouldn't get the Classe CT-SSP/SSP 800 av preamp surround processor if I were you. The CT-SSP does not have a USB input. It does have HDMI, spdif (coax digital audio), and optical digital (Toslink) inputs. Lacking USB input can be troublesome if you want to connect your computer to stream music files.
Don't get me wrong the CT-SSP/SSP 800 sounded great for two channels but I would wait and get a stereo preamp/DAC or a DAC + stereo preamp. From time to time I spotted a Classe CP 800 stereo preamp/DAC here on Audiogon. This one has USB DAC input and will perform better than the CT-SSP/SSP 800.
There are also countless other options out there as far as the DAC/preamp options. PS Audio Direct Stream DAC is awesome and has built-in volume control / preamp and recently there are quite a few of them offered for sale here on Agon. This will even be better than the Classe CP 800 stereo preamp/DAC.
Benchmark also makes spectacular sounding DAC for the money and they have built-in volume control as well.
