Volent VL-2, Hyperion 968 or Acoustic Zen Adagio

I use my system for 50% 2 channel and 50% 5 channel. The room is about 20x18. I use a Denon 3808 to drive the system. Thanks in advance.
Just got them two days ago and now I understand why everyone said I would need an amp. the b&w's i had didnt need the power but these seem to want more and better power.
Just to give you an idea, I use a 17.000 Euros set of amplifiers to drive my Hyperion 938. The better the amplifiers you are using the best the result you will get.
Hyperions belong in a higher class than their retail price would imply so try to drive them with high quality electronics....
