Well, tons of stuff at 7k for speakers. Is that 7k used? Then consider B&W 803D or N802, Von Schweikert VR4, KEF 205, Revel Salon, etc.
The CD choices at 3-4k used are also immense (Simaudio, Cary, Esoteric, etc) but I might suggest looking at some of the after-market modded units, and maybe buying something used and getting it modded for the same total 3-4k. Many great modders, ie, Modwright, upgrade co, Empirical audio, etc. Just my opinion, but wouldn't go for outboard DAC unless you already had transport/old CD and/or were looking to add NAS or Sonos/Slim Devices type setup.
Just some quick thoughts...
