Can you add a gap between the front doors and the bottom shelf?

Nothing that wouldn't look out of place. One thing I might consider in the
future is fan assisted air input up through the bottom shelf with fan output
somewhere near the top back of the unit. That type of air flow wouldn't have
any effect on the aesthetics of the entertainment centre.

ones are usually lighter and shorter, while class AB amps are generally
taller/heavier due to the large transformer(s) in them.

Going solely on that basis, it's an AB amp weighing in at close to 50 lbs.
At least that's what it felt like when I was struggling to lift it in place.
For now, I'm not going to worry about it. The entire back of the
entertainment unit is open. If and when I get around to closing it in, I'll
measure the temperature difference and decide then if I need to run some
type of additional cooling assistance.
