"Are there advantages to monoblocks? Maybe. "
The advantages are real in theory in regards to optimal sound and worth being informed about.
In practice they may or may not matter much from case to case.
And, other factors generally come into play that are more important, like convenience.
Few setups are optimized to the nth degree (well some on this site are perhaps) and still sound great. My system certainly falls into that category.
If I were a vendor selling products or services to others rather than your typical Joe music lover, I would probably pay the nth degree of attention to these things. Otherwise, it really may not matter practically.
