Music source is hidden in the media console. I stream to a Yamaha WCA-50 and take the digital out to a Minidsp DDRC-22D (using Dirac live below 300 Hz) before feeding the DAC. I also take the pre-out of my receiver into the analog input of the DAC3 L in HT bypass mode.
The Benchmark AHB2 is something I would love to use in my system. Not too long ago, I bought a Benchmark DAC 1 Pre, and I love it. Even though it has a few years on it, I find its sound quality outstanding. It seems it would rather hard to improve on it, but obviously there is better to be had. I'm satisfied with the old DAC 1, though.
I find the DAC3 to be audible transparent and it’s also one of the best measuring DACs on the market. It’s very flexible and makes a great preamp too while supporting HT pass through. I’d consider upgrading it if I can find something with equivalent performance and features but added bass management.
Awesome setup. As a Revel/JL guy myself, I applaud your choices! Not to nitpick but have you looked at other digital frontends? The Benchmark is quite nice but I can’t help but think there is more your system is capable of. DCS?
