Nick,
The dspNexus 2x8 HiRez DAC's that Danny heard at LSAF was a prototype with the flagship AKM AK4499's. These are the best DAC's I have ever heard and do digital volume control at a very high level of sound quality. There are 4 of the DAC modules in a dspNexus 2x8, so no need for external ones.
Seems like there maybe two audio shows in TX in 2024, LSAF and SWAF that Gary Gill is organizing. I am not planning on doing another TX show next year as I am trying for a bigger room at CAF2024.
Back in 2018 I wanted to bring my line arrays to CAF, but 4 ribbons broke when the speaker fell. They had to be rebuilt and did not make it in time for the show, so I had a big room and The Monoliths speakers. I made the best of it, but it was way to big for the speaker. I want a smaller room than that, but with new line arrays in work.
The upgraded Monoliths II speakers will be at AXPONA 2024 in the Danville Signal room. The idea is the new Radian Audio drivers replacing the original BG planars. Depends on when the updated LT3.2 planar tweeter is released as the original LT3 is out of production.
