So I've been looking into getting a USB dac and amp for a while as most of my music is on my computer and I am not too interested in getting a high end sound card. I also study computer engineering at school (I'm an undergrad) and I'm really getting interested in building my own.
I'm not opposed to designing my own from scratch as I know I can probably do it with access to the right specs, but I really think I'd prefer a well-documented kit for my first one.
Does anyone know of any good kits? I'm looking to keep my cost between $50-$100. This is a learning experience for me after all and I know once I do one I'll want to keep going.
If designing my own is a good idea, I really like the look of Twister Pear Audio's Opus dac but my biggest issue with using that schematic was that it does not have a direct USB interface and the interface that Twister Pear has online is 16 bit, not 24. I don't really see the point of using a 32 bit DAC with only a 16 bit usb interface. And not only would I need help figuring out the best way to amplify the output from the opus.
Any ideas would be great.
