No problem!
As I said, the intention of my post wasn't to try and convince you to get a sub (TBH I agree it's probably better to start without one initially for simplicity), but rather to point out that having bigger speakers wouldn't solve the same problems as a sub would.
In addition I thought it important to stress the importance of optimized placement and room EQ for sound quality.
Sure, there are several ways to go about this, though note that not all of them may have the same functionality, or integrate seamlessly (e.g. consider power on/off of all components, clicks/pops/noises during sample rate changes and power cycling, gain-staging, auto-standby, etc...).
These kinds of things may not seem like a big deal initially, but can sometimes become a source of frustration in the longer run so I thought it worth mentioning as well.
By the way - there are also all-in-one active speakers with HDMI or optical inputs, e.g. Kali MM-6 and Klipsch The Fives. As far as I know neither of them provide room correction EQ capability, sadly.
