For the RIAA EQ testing with the dspMusik, my DSA Phono One beta unit was modified for flat gain use to drive the ADC for DSP EQ.
Will be adding the RIAA EQ processing to The Monoliths digital crossover design to do both with the system.
This will be the first implementation of no linear phase digital RIAA EQ and digital crossover for a system to my knowledge. Neither the ADC or DAC's are using linear phase filter types.
Listening trials begin tomorrow.
