Hey guys,
After enough drama I finally completed my minimax (thanks tomb!) and bantamDAC which I built first. On the thread I started earlier, I built the minimax but was getting no sound output apart from heavy buzz. I booted into windows and found that the Dac/amp work successfully. Now I have another mystery problem. The moment I turn my amp volume past the silent point I get nasty buzz. Past the 3rd mark is painful and over the top loud. I read somewhere that if the buzz is coming from some problem within the amp, then unplug your sound source and see if the buzz is there. Luckily, once I unplugged the DAC the buzz was completely gone even with minimax at max volume. I assume this means a issue within the DAC? The only thing I can say about it is that I soldered the rca cables directly onto the board, making the bantamDAC usb. I separated the braid and only soldered the main wire onto the board. I'm guessing now the buzz is because I didn't ground them? No clue how to, do I simply solder the braids together?
The other thing that is weird is that the audio quality of the setup is rather low.
I know that the buzz/static sound is there, but apart from that it's quite poor. I still listen through my computers onboard, but this is a lot worse. I'm thinking it's because of the grounding issue, dunno.
Anyhow, thanks so much for all the help! I don't think I'd be this far on my own.
Hopefully we can iron out these last little bugs and start enjoying some good sound. :-)
