please help with amp and speaker selection

I'm trying to decide whether to buy a vintage Mac amp (SS) to use with my Carver C-1 preamp OR to purchase a used Simaudio I-5 integrated. The Carver is collecting dust so I'd like to use it if I decide to go the way of separates. Will the C-1 be much of a hinderance to the sound quality of the McIntosh? I'll be purchasing speakers after I decide on the amp so any help there is greatly appreciated too. I'd like to spend less than $1000 for speakers...used is fine too. My listening room is small - appx. 14X10. I currently have an HT system but the two channel quality is awful. I listen mainly to classic jazz, blues and rock. My source, for the time being, is a Sony DVP-S7700.

Thanks in advance for your time and tips!
