Your question can be addressed in the same simplistic form asked or broken down into more details. Simple answer yes an no. I like different artists at different levels. It is easy to measure as I start an album at at set level and as the listening session goes on I find my self either turning it up or turning it down. Detailed answer has to breakdown the rig. SS class A class A/B, tubes in the chain, types of power source in the amp ( I don’t get caught up in watts per as in my mind this is and can be overrated) then speaker efficiency. Some speakers will sing at low to moderate levels with the right amp and others crave high current high power and high volume. This reminds me of college in the 80’s with my Bose 901’s running a Sansui 9090 amp. The power supply on this amp could double as a welder if needed. The 901’s only made acceptable sound at ear bleeding levels.
So is louder better yes and no.
