Power amplifier gain issue

Hi all,
I swopped my Rotel 200W power amp for a Cambridge Audio 200W power amp and at the same relative volume on the preamp, the volume was considerably louder on the Cambridge.

From this, I deduced that the 200W is a lot more powerful than the 200W on the Rotel, which to me doesn't make any sense.

So now my questions :
Can the same wattage amp but with a different gain really have such a large impact on loudness?

But if the gain results in a much louder sound from the same relative position along the volume pot, and both amps have similar power output, then wouldn't the amp with higher gain reach full output sooner than the other?

I guess I'm just trying to understand what's going on here. I always assumed that two power amps of equal power output would have equal loudness as the volume was turned up, but I guess my assumptions are inaccurate or incomplete.
According to amp gain calculation equations from:

Anyone has ideas of it? Many thanks.

In addition to what you have described, good playback of this amplifier is very much influenced by the internet. If you have a poor connection, you will not be able to adjust the volume properly and the output power on this amplifier will be quite small. I advise you to contact Howly if you are experiencing poor connection. They are experts at not working internet troubleshooting. I am sure that if you contact them in a short time they will solve the problem and your amplifier will work.
