Choose Naim if you want to have full set including amp, cdp, cables and cap.
I am using rotel ra-06(70W, 8ohm) push CM5, at my 'wooden' ear ok! If want to upgrade, consider to buy over 100W to push CM5, e.g. luxman 505. Due to budget problem, I choose CM5 with rotel at showroom. I may add power amp if I change a bigger flat.
