Thanks for the welcome and responses.
Listensing space is 26ft x 15ft, with low ceiling of 90 inches.
In listenig sessions, the loudest I turn the volume knob is to about 70%.
From the answers, looks like I should get a more powerful amp if I want to crank up the volume. I don't need louder volume.
So if my current integrted amp drives my speakers to the max level I would listen without any clipping, I woulnt get any benefit in sound quality by upgrading to a more powerful amp beside louder volume? (supposing the quality of the amps are similar)
