With the money you are spending, you could easily get a pair of Genelec 8361a active speakers and be done with it.
I agree that active speakers are the way to go but there are logistical challenges with managing 12V triggers and wiring audio and power as you go to more channels. There are also limitations compared to something like the S360. It’s not about listening this loud at 1m, but having the linearity at further listening distances and those peaks in the 90’s of dB.
Remember when I said in my first post ... "We may at times appear to be blunt, but it's all in the service of clarity, accuracy and better engineering."?
When you start a sentence “with all due respect” it usually follows by something disrespectful. What I challenge you and ASR to do is to provide support for clarity, accuracy, and better engineering without needing to be blunt.
When you have a guest arrive to your home, it’s not fair for the guest to complain about the cooking but imagine the host also criticizing someone’s fashion choices upon their arrival…
It is possible to agree that you can hear differences between amplifiers while also agreeing that once level matched, frequency response matched, and phase matched, its inaudible?
Think about how you control dedicated separates if you were testing? You have volume control of only 0.5 dB. Think about level matching to 1 kHz sine waves via a multimeter but having different effective frequency response. Think about level dependent distortion adding a sweetening effect.
It’s not that the listener is doing it wrong (the comparison) but that practical realities prevent you comparing the same recording with different electronics and controlling the level. You essentially need to prepare two digital files to compare the two setups.
