My current speakers can output 120 Watt, so upgrading my amp to 2X130 will increase the power a lot I guess from 2X30. I will be adding about 6 dB more output. But I'll bring my speakers and power to the dealer and demo them separately anyway.
OK, I've got a suggestion for you. Go and BORROW the demo amp your looking at for your setup. Take it home and play YOUR amp for 1/2 HR playing music that you like and know, at the volume you usually listen at. Then switch out the amps, and play EXACTLY the same music, at EXACTLY the same volume. When we do it here we calibrate it with a SPL meter. If you don't have one it will be much harder. Remember that the volume knob setting has nothing to do with the actual volume. Either amp might be more sensitive, so you will have to set the volume by EAR. Now switch back to your amp and do it again. It's not going to be very much fun, but you'll get an idea of what kind of difference a new amp will make. In no way should you turn the volume up to see which one will play louder! That you already know, what your trying to understand is which sounds BETTER, which does not necessarily mean louder.

I like high powered amps. Always did. But I have heard incredible amps with powers as low as 50 watts, so I would keep an open mind before you jump to the conclusion that more power is always better.
