If I use 4.7µF / 200VDC GenI, the smaller caps must be the same 200VDC, in parallel ? Correct me if I'm wrong

I wonder what the amplification stage looks like between the DAC and the headphones, as Wolfson's papers all talk about hooking headphones straight into the DAC. Again, we refer to that corner frequency equation, and 22uF seems to work for my 4G with my Millett MAX. IIRC, the input impedance is something around 50K, so the corner frequency is pretty much obliterated at 0.144Hz. The surprising thing was how the 47uF BGs gave me so much more bass. If you want to work straight into the headphone jack, 220uF goes great with 32ohms, and the BG version sizes up at 8mm x 11mm. What were you thinking of doing? |
