Make sure that your system can play well at low volumes. This is really key for a bedroom system and sometimes difficult to achieve, as so many speakers need power to sound at or near their best. Speaker choice, in general, can be difficult as you will probably need to compromise (a lot) as to where you can place the stereo. This may mean near rear wall or inside a cabinet placement for the speakers. If this is the case, you may need to consider acoustic suspension speakers (preferable) or front ported speakers (not so bad) only. NHT makes some excellent acoustic suspension monitor sized speakers (SB1 & SB2).
Also, consider going with a quality 2 channel receiver or refurbishing a quality vintage receiver. Having FM available to you as a source is a nice to have when background music is desired and you do not want to play DJ. Receivers like the new Rotel RX 1052 or NAD C740 or even the Denon DRA 395 would work out nicely.
If you check out my system, I have evolved to a vintage Marantz 2240 receiver paired with a Music Hall MMF CD25 CD player and a pair of Omega Super 3 loudspeakers. The Omegas come in close to a dozen stunning wood and laminate finishes ... so matching to your decor should not be an issue. The Omegas are interesting in that they employ one full-range speaker ... super efficient and no crossovers. The sound is very lifelike and especially enjoyable with the types of music that typically get played in a bedroom (attempting to be a gentleman here folks).
