Special thanks to @rhythmdevils for taking us back to memory lane. The AMB Gamma 2 DAC was a wonderful sounding DAC during the infancy of headphone audio. It was available as DIY only; however assembled models could easily be found for sale. The DAC uses the old Wolfson chip, which is a good sounding part, but tonally it could sound all other the place. The AMB Gamma 2 DAC implementation has a bold sound with a minimum of digital nasties. The tone was its primary selling point. It was not the most resolving or nuanced sounding DAC however. I wanted to showcase this DAC because this is an example of how marketing practices prevailed over engineering. For those who actually thought NWAVGUY was a master engineer, looking to save us all from bad measuring gear by developing the ODAC, there was already one DAC design readily available from his arch-nemesis AMB or Ti Kan with arguably better performance. Those of us who have met Ti Kan know what an outstanding and humble dude he is. If there was any DAC that should have been the ODAC, the AMB Gamma 2 should have been it. This isn't member-berries, but rather of how we should learn from the bullshit of the past. Measurements forthcoming.
