This one has the option of switching in some DSP that adds several EQ bands and dedicated stereo subwoofer outputs. If you dont use the DSP, its not in the signal path, and you can still call yourself a purist audiophile. Have no doubts; this is a very unique product, and the performance is stellar. Speaking of switching, the CP-800 uses a switch mode power supply. Now, I know a lot of audiophiles rail against the idea of switching components, and I have been one of those people. But, switching technology has improved at an accelerating rate over the past few years, and it appears to be ready for prime time.

There is an LCD panel that shows the volume level, but also has a menu for you to select DSP options, such as the frequencies where you would like to decrease the level (such as a room mode). The volume control dial is huge, which I like, because I have big hands. There is also a USB port, which is configured for connecting to your iPod (the oldest versions of iPods will not work with this port, however). The rear panel: You can see the on/off toggle, a grounded AC socket, digital input connections consisting of a USB jack, XLR, three coax, and four Toslink optical jacks. There are also trigger jacks, and RS-232 jack, and an Ethernet port (for future use). Analog inputs include three sets of coax and two sets of XLR. Analog outputs are two sets each of XLR and coax. The USB jack on the rear is asynchronous (as is the one on the front), and is for use with a computers digital music output (so, consider this input a USB DAC).
