I’d love to see Taiko or MSB or similar take on building hard-core audiophile DSP systems. My experience is that part of what we attribute to “DSP” is less about digital processing than it is about less than state of the art internal power supplies, clocks, jitter reduction, etc. etc. in the products we are using to hear and evaluate DSP processing.
One experience brought this home to me. I was using a DEQX to provide digital crossover functionality for a custom built two way line array. This was only crossover functionality and not room correction. The DEQX did some “magical” things for the sonics, but it was also “taking away” some of the magic of the (simple, purist) analog crossover. In the end I still preferred the analog crossover most of the time. I then heavily modified the DEQX with better internal power supplies, better internal grounding schemes, high-end input and output transformers, better clocks, better shielding, etc. etc. etc. Following those mods the DEQX was better in all ways than the analog setup. What I had been attributing to “DSP” was more a result of the types of things audiophiles obsess over and not “the math manipulation”. My recent experiences with the SwitchX and AppleTV-X products were similar - the sonics coming from “digital” products improved materially with upgrades to their “non-math” components.
I suspect that if Taiko or MSB or Wadax or the like took this on we’d be having a different discussion about the drawbacks of DSP in high end two channel systems. (And if anyone reading this wants to take on a Trinnov upgrade project DM me!)
