Speaker amp to active speakers

Sure that would work.
They have a remote for volume control. Just speakers and remote is what i think you are looking.
Easy option with no extra hardware.

Depending on overall budget there are few other brands as well that can take optical audio (toslink) and have remote. Kanto is in the affordable range money wise 420$…ish?

There have been few issues with Kanto speakers even in here.

The more expensive ones are few hundred more than Kantos, going to 1k - 3k range and even to 100k options but i think we in the few hundred-dollar range.
