Do you need a DAC for internet radio only?


I'm thinking about trying out the Squeezebox Duet but I think only to have the ability to listen to Pandora, Rhapsody or several internet radio stations at this time. I have a very nice Modwright CD player and an older Sony Jutebox CD player as well. I know the jutebox would benefit from a good DAC but I only listen to it now on random for background music which would be the purpose of the Squeezebox. Does the Squeezebox benefit from a DAC when only listening to the internet? At this time I do not think I will rip my CD's to a hard drive.

I'm not adverse to a DAC and if there is an improvement, I would consider a DAC in the $500 range. Suggestions if appropriate would be appreciated as well. Thanks, Mike

Drubin, if you like jazz, there are killer stations in Switzerland, Spain, Japan, Brazil and France that are broadcast over the web that sound fantastic. Lots more jazz stations around the globe that are available to you. Just do a web search of "internet jazz radio stations."

I have a squeezebox (Benchmark dac) and have no drop out/buffering issues w/internet radio. While I wish they were wav files, they actually sound decent through the dac. Better than mp3's, which they are. W/o the dac...they sound like mp3's.
Thanks everyone. I think I'll start with the SB only, play around with the Internet radio, rip a few CD's, save up some money and of course, unable to help myself, buy a DAC!!!
