Best used DAC under $750.

Integrated Amp ideas for Dynaudio Special 40's
The Job Int integrated will smoke everything Peachtree makes. The Nuprime IDA-8 isn't even in the same league as the Job Int.

@daseldin - Currently using VH Audio Pulsar Cu RCA Interconnects. Vampire Wire also makes good reasonably priced interconnects. 
MacBook Pro Playback distortion
What does your mac pass the signal to? An external DAC? If using an external DAC, how is your mac connected to the DAC? USB cables do make a difference in sound quality. Cheap usb cables will sound like garbage.

Has anyone added a small subwoofer to 2 channel and been thrilled with the result?
@lance-baker The op stated he wants to 'add' bass to his 2 channel system, not win a SPL competition. DVC setups are unnecessary for what the op is looking for. The op also stated his room is 12'x13' so it's not going to take much to add some addi...

Nuforce STA200
I'm running the STA200 with PMC OB1 (87db 6 ohm) with a NAD M51 as the frontend and have no complaints. The amp will drive the speakers louder than my neighbors would be willing to stand.
