My opinion is that, I wouldn't worry about 'hearing' the amps. They will all sound virtually the same unless you plan on playing them so loud that you discover the limits of their capabilities and that would be pretty loud.

If you like it LOUDDDDDD and need to fill a huge room, then more wattage will take you further. Otherwise, pick the one with all the connectors and features you would ever think to need.

There are some emp & receiver experts here who can help more. The above is just to get you thinking more about future proofing the amp.

With great power comes Awesome irresponsibility.
