It is not just about SPL. It is about headroom, dynamics, and PRAT. I have had Stages/Mini Grands for 18 years with different amps. I never heard the panels come alive until I put serious power on them. I am NOT talking about 250 watts into 4 ohms. I am talking about 500 or more. If someone has not heard Stage speakers with serious power from amplifiers that have good control I am not sure they are aware of what the speakers are capable of. That is my opinion based upon my actual experience.
Again I am not talking about SPL because the speakers do have a maximum SPL that no amount of power can exceed. In fact, it is possible to have too much power. I only listen slightly louder now than I did with lower power amps but the dynamics and realism are dramatically improved and even at low volume the detail and PRAT is improved although that may not be a function of power, just a different amp.
Please note: I am talking about SS power. I do not have enough experience to comment on tube amps and power requirements for Stage speakers.
