Is DEQX a game changer?

Measuring outside gives plots on the software where the first reflection is quite distant and easily identified - this helps greatly with the accuracy of the calibration

Measuring inside does colour the result and when I compare by listening, an inside measurement/calibration sounds more hollow and artificial whereas an outside measurement results in very pure and neutral sounding music

If your dealer is willing and the weather permits, I strongly recommend you take this option. It will really show how special this processor is

"I doubt schlepping the speakers and amp outside is an option either."
Then you will not hear the best that the DEQX has to offer.

"If it took me more than a few bars to hear the change interest would be lost."
Then you have a short attention span and the DEQX is not for you.

"No need to ever remove it.."
Of course not, but doing so will remind you what changes are being made by having it in the playback chain.

"Although it took me about 6 months to fully understand and perfect everything."
Exactly!

If you measure indoors, DEQX will hear room effects and the calibration will be much less accurate & the finished result compromised. It can still be effective, just not as good as it should

Here's a youtube video of someone doing it from their car (white coat optional !!)

If you live in a house with a garden then great & use an extension lead, if you don't then I guess you have no other option for now

So, if you have to go with an indoors measurement, lift the speakers up in the air ('platform' in the centre of the room, put the speaker on it and measure one at a time of course, making sure you record which measurement relates to which speaker), preferably angled slightly upwards - cover the floor in front with cushions and other soft materials to kill the reflections as much as possible

If the dealer is doing it correctly, he will know all this anyway

I did mine in the driveway. Buy yourself a decent moving dolly and attach some protective padding. Should be under $100 total. The outdoor measurement can be done with the speaker on the dolly. All you need is a speaker, an amp, and an available outlet. The DEQX rep will take care of everything else.
