Yeah, in 2021. Since then, a bit has happened.
MacIntosh most recent AVP (mx200) is not compatible with DLBC, does not have streaming features, can take 2 subwoofers only on RCA, has less channels, no zone 2 and 3, worse HDMI and less connections, less configuration options (LFE routing, center wide...), no Auro 3D... Yet it's "just" around a grand less than an AV10.
Sure, the raw performance and build quality is there, but so is in the AV10.
A lot of those lacking elements could have been implemented on the MX200. The compatibly with DLBC should be a given due to the supposedly discrete subwoofer outs. If there is a really useful XLR is precisely for a subwoofer, as longer cable runs risk noise a lot more than just speaker to amp RCA's.
And sure, no need to build a platform like HEOS, something as humble as Chromecast and Airplay compatibly could suffice. LFE routing and center spread? That's just software. No need for extra channels, Auro or even multi zone to keep a lower price? Sure, not a bad move.
