Raspberry Pi + DAC combination under 100?

Hey all!

I'm looking to get a Raspberry Pi/BBB as a digital source to an upcoming diy setup. Im on a pretty tight budget, and wish to squeeze the best I can get out of a $100. This is including the Pi, DAC, power adapter(prepared to upgrade later if required), upgrade caps if needed.

I have considered Duriosound, Sellarz-based tcxo 9023 and IQAudio Dac+. The audiophonics and mamboberry shoot out of my budget.

If this were to feed directly into an amp, maybe an Amp Camp Amp, would the impedance matching be a big bottleneck in performance? If so, what is the best way to match these sources( cheaply). If it comes with added volume control, I am happy to bump the budget up to 130. Will a passive preamp help matching impedances or does it do nothing but volume control?

Anyone with experience with these dacs, please help! Thanks

See the moode thread; drive everything via your browser, including volume.

I have iqaudio dac+ and that's driving my modulus-86 chip amp with no problems.

My only issues with the current setup is the noise that either the pi power source, or the network is creating - there's a faint background buzz - not ground loop.

If you are using a usb wifi adaptor with your pi rather than an ethernet cable you might have a similar problem to mine.

Very occasionally, and usually when the pi is busy on the network such as updating a large music database, I had faint crackling in the speaker. Suspecting the wifi adapter I connected it to the pi via a 30cm usb extension so I could position it away from the pi. I haven't had an issue since.

If you are able to use ethernet so much the better.
 
Its DIY DAC. Digi Clone (WM8805) and TDA1387 based. :D
