Amazon germany stated 100W - 200W AMP required for the 509 DC. Like every one is saying - avoid clipping...


Anyway, I found the Yamaha RX 1030 to be the one you need as it has A and B Front speakers. It means that you can bi-amp your 509 DC and take some of the load off and put it to B speakers. So try find one like this, it would be good.

Best deal and it's Bi-amp capable - http://www.crutchfield.com/S-PFnSFJ7Xbgn/compare_033AVX2000_532AVR3700/Denon-AVR-X2000-IN-Command-vs-Harman-Kardon-AVR-3700.html

These comes with zone 2 pre-out if you want to add extra amp later

You wrote "every meter further away requires a doubling of power". Your formula is just a mathematical representation of the same statement.
I'm happy to be corrected, but I'd like to see something to back that statement up.
The required power doubles every 3dB.
For your statement to be true, there needs to be a fixed loss of -3dB with every meter of distance. This is a linear relationship. As a formula if you like l = -3x where x is the change in distance and l is the loss in dB.
This is not the case. The loss is -6dB when the distance doubles if there are no reflections. In a room the loss is less because of reflected sound, but the loss is logarithmic with distance rather than linear.
The point I was trying to make is that the increase in amplifier power required to go from 2m to 3m is more than the increase required to go from 4m to 5m for instance. I don't see how the -3dB per meter can be accurate.

I'm sure these are good, but they seem like more than a normal home user would need.
Bi-amping a set of speakers is of arguable value. Then driving the speaker on one amplifier output most of the power is used by the bass driver. The mid-range and tweeter use far less. By splitting the input, the channel for the bass driver has a little extra than it would otherwise. The channel for the mid-range and tweeter will hardly require any power.
Again, happy to be corrected if it can be backed up.

You are right but I'm guessing the woofer above the tweeter may be the Mid, if that so id the mid and high takes about 15W to 30W of power then what's left from 80W or 100W.?

Also, the Denon receiver is a good deal, may be he can use his savings for shipping.

The Harman Kardon i linked previously is cheaper. its up to OP to decide what he wants.
