I agree, room correction won't always be necessary. My five cents: - To fight room modes, I just play pink noise and run an RTA freeware on my phone. Shows me well enough where I've got to reduce bass. Big value of that method in small rooms. - In terms of bass nulls it's probably more worth to move the speaker to a different location - small speakers with not much bass won't create bass resonances in big rooms, no need for correction :-) - Above 300Hz I get different FR when I move the mic only a little bit. Not much worth correcting against room reflections there. - For some speakers the FR correction above 300Hz might rather smooth out speaker imperfections than room reflections. And some speakers sound boring with a linear FR. I'm kind of "Team McGowan" in that aspect - If you clap your hands in the room and hear the reverb then don't bother with room correction. No precise sound to be expected in that room.

Great software indeed! I own it for a few years already. At first Reference 4, and now SoundID Reference in a kind of hardware configuration you have demonstrated. It works great 👍. The only (major) problem I still have is that it doesn’t work over UPnP/DLNA in the new SoundID Reference version anymore. I’m still in very good contact with them to solve this (great service, anyhow!). For headphones it works great already, but not over UPnP/DLNA, unfortunately. If they get this working, it’s certainly a great 👍 tool for a lot of HiFi enthusiasts!

I have a dual purpose system...for 2 channel listening and home theater. This system is in my family room, which is imperfect in a number of ways. Your point about the benefit of using room correction, in a room where room treatments aren't possible, definitely applies to my situation. In my system, i use Anthem ARC. As i can quickly toggle room correction on and off, it's interesting to hear the difference it makes. Looking at it pragmatically, I'm not sure why someone would say it's appropriate for multichannel but not 2 channel. That really makes no sense...as the vast majority of listeners have imperfect listening spaces that can be improved by room correction software. It will be interesting to hear your thoughts when you feed it through your H390. I have wondered how that would have sounded in my space, although i no longer have my H390 to test that. I do know that there is a profound difference with my Anthem/Parasound A31 setup.

Thanks for the walkthrough! As there is not a lot of info to be found yet allow me to ask a few questions since I am considering buying the A7V specifically for that feature: 1) Is it possible to do the same SoundID procedure a third-party measurement microphone (assuming it has a calibration txt)? I do not really get the purpose of the reference number of Sonarworks mic... 2) Is the separate Volt USB interface required? When doing measurements with REW and my mic I just connected the mic via USB-C and fed the speakers seperately. 3) Last question: I read the speakers have to be connected via cable but I assume this is a separate step from the measuring itself, right? Asking because my router is in another room and I would need to take the Adams over there to connect them in order to feed them the profile. Appreciate your answer :)

I have had good luck using the PEQ filters in the Wiim. You still need a measurement mic but REW is of course free..u just need a little patience to learn the software or find a good guide.

I was wondering what is the impact od external dac on overall quality of the sound. I am a bit confused because A7Vs have an internal 24/192 processor build in. If I decide to upgrade to those speakers would my RME ADI-2/4 Pro Se make any difference?

I'm considering a pair of A8H's for HiFi/Home Cinema use. Do you think those would be a good fit as the A7V's are?
