As my ears get older I'd like to build a dedicated headphone set. The use of on or in ear headphones allow for accurate filtering as per David Griesinger's method ( http://www.davidgriesinger.com/ ) . One of the things I'd like to connect to the set is a record player using Daniel's old VSPS board.
Sadly I see that the DSP add on board does not work together with the DAC+ ADC. The DAC+ DSP does no analogue. Is there a simple way out? Stack the DAC+ ADC and the DAC+ DSP, even if it is waste full? Or just do the DSP with the RPi? Does not feel like an elegant solution.
