Since you chose the Onkyo cd player I would suggest the Onkyo 9555 int amp. The amp is class D and has a built in phono pre-amp if you ever want to return to vinyl. The amp is good sounding for the $500 discounted price. I have also been having fun with the Monitor Audio RS6 speakers. MA came out with the RX line so dealers are discounting the RS stock. Bass is well defined along with a detailed midrange and a wonderful treble better than I remember in my Smaller Advents. The Onkyo will drive them easily.
