I don't know, they got the specs wrong on the DACs for the MRX receivers. It's supposed to be 32-Bit/768 kHz DAC not 24-Bit/96 kHZ DAC. Luckily it was fixed on the product page. \I found a couple good reads (reviews) on Audio Advice. Audio Advice is one of the two authorized online sellers of Anthem products.

What do they mean by classic Anthem sound? Is it the sound from the first gen Anthem MRX A/V receivers and older Anthem processors and amps or is it the sound from second gen and newer from their MRX A/V receivers? I'm really curious to how it's going to sound like.
I own both the MRX 300 and the 510, (first and second gen) and they have completely different sound that you would think they are from different brands of A/V receivers. The 300 has that deep bass that slams hard with great dymanics and detail while the 510 has a rich warm sound that pushes for greater detail with modest bass sound.
So, how is the new MRX A/V receivers going to sound like? Only time will tell until we get our hands on it.
