So, I have to select an amp to power my front set of components. I can either select the KS300.2 which can give me 180 watts to each channel at 4 ohms while the XXK can provide that in the bridged mode. So my question to you is which is more efficient and which would you choose. It's about a ~$70 dollar difference between the two with the Ks300.2 being $329.00 and the XXK4050 being $260 new and $220 used.

Honestly, the only reason I'm considering getting the Ks300.2 is for symmetry purposes. Even though, the XXK4050 is prettier.
