Yamaha RX-A4A, Tannoy Profile 638, Yamaha NS-300 Sub x 2, WiiM Pro x 2, Sansui Graphic Eq. I like the way I was able to integrate Sansui Graphic EQ via WiiM Line Out thence to the line-in of the RX-A4A. I was also able to connect the same WiiM Pro via SPDIF/CoAx to the same RX-A4A to utilize the AVR’s internal DAC. If I decide to use the WiiM Pro’s internal DAC…I just use the by-pass button on the EQ. Sometimes , I just love to tailor the sound the way I wanted to hear.
