Nick,
Thanks, but I am not at AXPONA 2024.
Danville Signal in room 356 has the Magnepan 1.7i's that I helped with the DSP crossover design for tri-amping them with the dspNexus 2x8 system.
They built the AB switching box for the demo. All the amps are the same as well as the front end uses all 8 channels of the dspNexus 2x8. Two channels are just direct DAC connections to the amps driving the original passive crossovers and the other 6 DAC's are the 3-way DSP crossover to the amps.
Feedback so far is that the demo is showing the listeners how not subtle the difference the DSP crossover can make when it is really at the state of the art.
