Classe SSP 300 vs Parasound C1 ?

From personal experience, I'd suggest the SSP 300 from Classe. If you can hook up with balanced XLR cables, I would suggest you go with the Classe SSP-600 and leverage its balanced bypass XLR functionality. I owned the 600 and loved it for 2-channel as well as home theater. I later added a CP-700 2-box Classe pre-amp (which I still have) to further serve my 2-channel only listening needs...

From personal experience....2-channel and multi-channel sound quality, imaging, musicality, sound-staging, dynamics, overall fit and finish, intuitive nature of the touch screen menu system and configuration options overall, levels of customer support and assistance I've received on several products, their reputation for excellent customer support, etc....I've also found their DSP pre-processing and post-processing for DD and DTS along with THX and THX Ultra2 post-processing to be of superior sound quality.
