Unless you own all ARC system (Pre and amp), I wouldn’t recommend pursuing a ARC DAC 7, 8, 9. I used to own DAC9 in all ARC system (Ref 6 and GS150). Also, you may run into USB audio compatibility issues with ARC DAC’s. ARC didn’t adapt to USB 2.0 protocol until DAC9. Even the early production DAC 9 had compatibility issues with USB audio. ARC was nice enough to upgrade the digital board for me at a reasonable fee.
I eventually got bored with ARC house sound and overhauled my entire system within 6 months of living with ARC. Others may love ARC sound but it wasn’t for me.
