Don't overthink this and run down a few rabbit trails trying to make that receiver work properly, unless you enjoy all the testing and placement and have some time to kill
I concur with MC and the others that have already indicated the receiver is your pain point
I second the suggestion of the PS Audio Sprout integrated amp, $600ish and they'd probably give you a few bucks on the trade in of the Akai
I run a Sprout on a 2 channel B system with a pair of KEF Q750s for my TV and streaming Tidal and Qobuz via Bluetooth from my phone
It's a great price performer, easy set up, not fussy and SQ is worthy
For extra added pleasure a good middle of the road power and speaker cables was like putting big boy pants on the Sprout
