We need to define a couple of things.
What is your top listing SPL?
What are your speakers, what is the sensitivity, power handling?
Music source?
Think you might need a whole new system to keep you happy. My amp is 200w high current, but I have 100db sensitivity on my speakers, they say they top out at 116db, On my setup, you cannot be in the room at 70% volume. It's uncomfortable. Most of my listening is around 1w of power, but at my listening spot is 70ish DB.
