EP#108: Crazy Transistor Contraptions

  • Stephen
    • Midi Woes
    • Atleast the Teensy is fast
  • Parker
    • DAC testing update
      • Interesting results looking at the spectrum analysis of the DACs
      • Film caps suppress harmonics better but let more low end frequency through
      • "Audio" grade parts have a higher response over the frequency band
      • All the DAC load outs have a flat frequency response
      • Blind testing resulted in listeners picking the cheaper passive load out for the DAC saying it sounded more "spacious"/"open"/"dynamic" compared to the film caps.
  • Rapid Fire Opinion R.F.O.
