I don't believe I've heard first-hand a QP with Larini boxes installed. I imagine it would instantly make my decision for me. Comparison videos are the next best thing, though they don't seem to exist as proper comparisons. It's not necessarily volume I want, it's the voice of the Larini's I've heard second-hand which I really like. Loud or quiet, it just sounds great.I know exactly what you are talking about... Have you heard a QP with Larini boxes in person? Was that too loud for you already??
