Consider looking at the Dared i 30 integrated with built in DAC. I believe it can be bought new for a reasonably low price, and will sound much better than the onkyo. As for speakers the wharfedale EVO (40's or 50's) are a good value. Quad 22L2's are nice, and a fav of mine the KEF 104/4's or reference 4's are great. Speakers, whatever brand you go with are probably best bought used. Don't forget that you'll need to buy some speaker cable too.
Good luck
