Help Choosing DAC


Hi, I have a Marantz 8b amp which I want to stream digital files from my computer. I plan to purchase some speakers (probably B&W's) used for 1500-3000 and would like to find a DAC that makes sense in this price range. Do some DAC units have the preamp built in? I am wondering if computer to DAC to amp is the right way to do this. Not familiar with DAC brands or features at all. Also what file type is best to build my library with. Thank you.

An example of a Dac with pre is the Burson conductor, it have 3 gain settings + lots if inputs for PC users. (USb/coax) a solid unit.
Hi- Thank you for all the info. I will look into a DAC that will allow me to go straight to the amp without my preamp in between.
Benchmark DAC1 HDR

World class DAC with preamp functionality and high quality headphone amp.

The Dspeaker Antimode Dual Core 2.0 ($1200.00) is a preamp with a built in dac and room correction. You will need an outboard device for streaming, but the D/C does have a USB input. Match the USB input with an IFi IUSB ($200.00) and run the D/C with a 12v linear or 12v battery power supply and you will have a very good sounding system.

Good luck
