Are we talking about the same Nick here:Further detail:
Nick of Anthem and the manual both state that the AVM 60 does not downsample to perform room correction.
Here is a quote from Nick of Anthem in the AVM 60 thread: “No downsampling either with ARC, bass management, and AnthemLogic running in any combination, including all at once. For any additional concerns please contact tech support, thanks.”
The manual also says on page 35 that it doesn’t downsample for ARC.
But I’ve read elsewhere that if you add other surround sound modes on top, such as Dolby Surround or DTS Neural X, it downsamples to 48/24.

: If using ARC, am I correct in understanding that if I theoretically feed it a 192kHz source, then the MRX units will downsample to 48kHz and the pre-pros will down sample to 96kHz? In other words, none of the models will be able to apply ARC at the native 192kHz?
Nick Platsis: This is correct, and for the longest time AVM/D was the only unit on the market that could operate room eq at higher than 48 kHz.
Audioholics: If I'm using the built-in ADC (Analog-to-Digital Converter) on the receivers and pre-pros via one of the analog inputs (let's say I'm playing an LP) and I choose to apply ARC will the units likewise down sample the incoming analog signal to 48kHz for the receivers and 96kHz for the pre-pros? Let's assume that there is no recording going on and I don't need to match a destination format.
Nick Platsis: A/D conversion in MRX is to 48 kHz. In AVM/D, it is according to the ADC setup menu. The selections range from 44.1 to 96 kHz and as a side note 176.4 and 192 weren't included because all they do is capture more noise. There's no extra audio signal to be had up there from an analog input.
The thing about "down sampling" can be tricky. If most do it with 48 kHz, then for those who do 96 kHz they might conveniently tell you they don't down sample when actually they do, if you feed it with 24/176, 24/192 or higher such as many flac, wave, dsd files available on line.
To me it is a moot point because it is proven that if processing power is limited, it would be best for the manufacturer to go with 48 kHz instead of sacrificing something else more important. It is however, seemingly impossible to get many Audiophiles or even just Audioholics such as me, to willingly accept down sampling to 48 kHz. That's the same idea as trying to get me to accept Yamaha's THD+N anomalies Gene found on the CX-A52 and now the RX-A6A. I know it would not make any audible difference to me, but I won't go for either one, not until the A53 get tested and got verified that issues have been addressed successfully
