So it's the same operator, who knows how to run a cal process, and the Pro delivers a better result.
As to why, well a good calibrated mic is just part of it, but a rather minor one IMHO. The real reason for the much more cohesive soundield is likely due to the algorithms having access to much more CPU horsepower, able to run a more complex algo, or just many more iterations thanks to CPU availability and the operator is a pro and not some antsy consumer who will not wait more than x for the calculations to end. One more factor could also be access to more data from the samples, as the AVR only has so much RAM, vs. the PC-based app with access to gigabytes of RAM.
Another benefit of Pro is what seems to me a much more accurate delay and timing in the setup/corrections. Maybe they do multiple cross-speaker passes to work out timing and inter-speaker effects. To me, this is a core of why Pro is better, as getting timing just right is a big deal when doing 3D audio.
Then you add the flexibility of personalized target curves, and the results are pretty sweet.
yep no brainer to me for the denon avp and 8802a essential I would say
experience repeated with 7702mk2 and 8801 as well as I found pro calibrating

For sure, but at a cost $$$$$. An Altitude is on my wish-list
absolutely .... though we are starting to get this on likes of nad. and anthem does pretty well too ... using calibrated mic and their ARC
"On a more complex level, ARC is a proprietary digital signal processing software that works with a specially-engineered calibration microphone and your PC or iOS device* to quickly and easily optimize audio for your unique listening space. Anthem engineers developed the ARC system while researching how to replicate the audio-lab standard of performance in non-lab environments. This groundbreaking research was conducted in conjunction with the National Research Council of Canada, the Canadian government’s research and technology organization."
"ARC Mobile allows you to optimize your ARC enabled speakers by using either the internal microphone of the iOS device (for basic room correction) or an optional calibrated microphone*. Optional calibrated microphones, which connect via headphone jack, will be included with select products from Anthem, Paradigm, and MartinLogan. Please refer to the product user manual to see if it’s included.
The ARC Mobile app is available for free to iOS users on the Apple Store, and is now available in public beta for Android devices. The app supports Anthem’s STR Series (STR Integrated & STR Preamplifier), Anthem's MRX Series of AV Receivers (x10 & x20 versions), Anthem’s AVM 60 Pre-Amplifier / Processor, Paradigm’s Premium Wireless Series (PW AMP, PW 600, PW 800, PW Link, PW Soundplay, and PW Soundbar), and MartinLogan’s Wireless Ensemble (Verse, Forte, Unison, Bravado, and Cadence)."
they seem to manage an iOS device use along with calibrated mic. a complete cop out I would suggest you have to have one or other in this day and age. why give up competency of calibrating ... with a calibrated mic
just because you want convenience of an app.
in any case am sitting pretty happy here... with the 8802a ... dont need no app or use an uncalibrated mic and its doing a great job on 7.1.5 so not like am left wanting.
but that said I would still look forward to a true flagship from marantz. D&M has done it before and am sure can do it again
