If sound quality is the most important parameter for you, you should consider purchasing a Terratec 512i Digital, not a Delphina. Terratec 512i sound quality is much better then that of Delphina's. If an MP3 decoder is a must, take a Delfina and connect it to the clock port. You will need ribbon extension for the clock port to use Delphina with Power Flyer.
