The only benefit is if you have patchy wifi. If you have a weak wifi signal, or interference from neighbours wifi, you’ll get packet loss and latency which could result in streaming issues. Like, the music stopping and caching for a second or two. If your wifi is fine, use it.
Streaming music uses fuck all bandwidth. Ethernet is recommended for streaming 4K video for sure.
Yeah. You can obsess over flat frequency response results, but you don’t listen to graphs.
My personal listening preferences line up closely to the Harman curve, so a boosted bass and warm rolled off upper frequencies. I’d likely much prefer OP’s EQd setup.
OP’s non-EQd results are textbook V shaped, which plenty of people enjoy. Neither one is better than the other for subjective enjoyment. Go with what you like.
The software version is expensive compared to other ways to have Dirac.
The Dirac Live Processor (the PC/Mac software version) costs US$349 where as a Minidsp DDRC-24 costs US$400. You get more flexibility with the external DSP option and end results are identical.
You’ll need to buy a UMIK-1 mic for either option as that’s needed for the initial setup. It’s $50 when bundled with the DDRC-24 or $79 bought individually.
Minidsp let you transfer Dirac licensed between their devices.
