I can start with the $89 Aiwa XC-30M, XC-35M, or XC-37M Five Disc CD Changer used as a transport for any DAC with a Delta-Sigma design. The MSB Link DAC is a Delta Sigma DAC, so if you pick up a Link DAC-1 for $150 used, you can have a nice setup with the Aiwa for under $300 (including the digital cable). Put a 5 pound bag of sand or lead shot on top of the Aiwa as a tweek and maybe some vibrapods (another sleeper at $6 each) New Aiwa's are available on eBay for around $55 usually.
The $250 B&W DM302 speakers fits the bill also.
For preamps, the Conrad Johnson PV-10 mentioned above, along with the Blue Circle BC21.
For amps, I have being playing around with Blue Circle's new "entry level" CS power amp for a couple weeks in my home office/den system. If you don't need the extra power, this little amp does not give up much to the BC22 that cost $1000 more. Adding the BC62 power cord to the CS takes it to another level. (I guess I should post a review of it!)
For cheap cables, I really like Stu Wein's MAS Black and MAS Grey at $50 and $85 a meter pair respectively (new). Right above Stu's are the Millersound cables.
