when you look at speaker power handlig capacity it does not mean you cannot use a higher power amp. It just means you cannot throw more than 200w at your speakers.
Then you might ask why do I need more power? the answer to this question would be headroom. It is easier for a 400w amp to output 200w to your speakers than a lesser power amp.
But, when considering amps another quality factor which is very important is current capacity. Being able to handle high current peaks translates to more dynamics. Part of this can be checked on how much capacitance (generally shown as XXXXX micro farads) and overall design. That is why I recomended not only more power but equal or more quality build. Generally amps that can handle 4ohm and lower are better in this respect.
Please note that at one meter distance your speakers are capable of around 88 decibels with only one watt fed to them (this is the sensivity).
So what all this means is that you can get amps with equal power specs from those on this receiver but with a much bigger transformer, current capacity and overall quality design. That is what you should look for in a amp.
I have a Haffler 500 heavily modded which can handle 1000w at 4ohm for front L/R. It's toroidal transformer has an output capacity of 90volts (a simple DVD player puts out a 2volt signal on average). I have this because when listening to music I do not use the receiver at all. I have a Preamp connected to the player and amp. when on HT use the preamp is set to bypass and the receiver controls volume etc...
For the center channel and passive subwoofer I have Sunrise Lab Power Amp
which has about 680W per channel in 4ohm.
The surrounds are powered by the receiver. Of course my dream is to have good monoblocks for each channel but since I do not print money, for the last 10 years it is what I could put together. The results as it is are already very good but I have the upgrade bug so...
