@grislybutter.... Friend Gb, I'm likely to be the worst case scenario to comment on integrated amps, since I've never owned one....
Began with a few receivers, the last being a Marantz...followed by a Kenwood 'L' separate system with the mono amps at speaker-side...
Since, I've been using a distribution amp that allows to bi-, tri-, or even quad lines from an active Xover.....not to mention all that's 'upstream' from that amp.
If I did anything, I'd move onto a better version of it, or duplicate it; I'm a believer in the 'first watt' concept, and dist amps are generally <100 rms which I'm good with.
To drive subs, I apply an 'in-hand' receiver with tape in/out to use it's higher power level potential.
Yeah, not so SOTA, but I'm generally happy with the results.
As a 'kinda-phile' that wears aids ( really nice ones', tho' ), having to be able to hear the 1st violinist sweat isn't my goal at the end of the day...🤷♂️😉
Rather than BS anyone, I guess I'll just have to party-poop the query.
Mia culpa....
