Somehow this hasn't been brought up either here or in the other thread, but it's analog which just the approximation.
The universe is quantized all the way down - matter, energy, time, and space.
It's just that usually the individual quanta are so small compared to the scale one is working at...
DSP actually lets you do a lot more.
Case in point, active speakers usually "cheat" by boosting the bass past the system's natural roll off and then adding a limiter so you don't unexpectedly damage the woofer. This limits maximum usable SPL in one way or another, either by compressing the...
Definitely need more than just an engine and tranny swap. You'd basically be replacing or very heavily modifying everything but the body, but that's the most important part so no big deal.
Kinda like this awesome audio related resto-mod.
What's the turntable equivalent of this?
The lack of products integrating useful DSP is leaving a lot on the table, but I still think we need both. Plain old high SINAD is pretty useful on it's own for avoiding hiss when using pure digital volume control and for DSP headroom.
Also firmware/software usually ends up being the hardest...
Multichannel music is definitely better in theory, but not so much in practice since there's so little content. Maybe this Atmos thing will keep going and that will change. Maybe it will die out like quadraphonic records.
Maybe you're lucky and what's currently available matches your tastes...
It's not quite a loudspeaker management system, but I currently run my speakers through a BSS BLU-160 which is being criminally underutilized since I haven't had the time to implement all my original plans for it.
The first few batches of the original L30 could fail and burn out the voice coil of the attached headphone. IIIRC they were just dumping straight DC across the output. All the gory details are buried in the 260 page thread.
Several of Schiit's models have had similar a reputation for blowing...
