I've just got myself a DAC+ Pro to connect my Volumio RPi to my old vintage Yamaha amp with. What I was wondering: The product photos all show gold plated oscillators for 44.1 and 48kHz frequencies. But the photos also show HW version 2.2. My DAC+ Pro is version 2.6 and it has those two oscillators, but they're black and not gold plated.
Are there different versions which are not accounted for anywhere? Especially as the gold plated oscillators are advertised as a key feature, I'm wondering how this can be...
