Coxhaus, I am assuming that you bought new speakers?
If so, they will need many hours of playing before you can evaluate them.
I have a 25' X 17' room with Andra 2 speakers. I am using a Pass Labs X350.5 and it has plenty of power for the Andra's.
I would think the Pass X600.5 would be even better. The older Pass 350 and 600 were not as warm sounding as the new .5 series so maybe thats what your friend had.
Anyway, I agree they need power to sound there best, but they also need break in time.
By the way, I own Synergistic Reasearch cables and preferred them over the Valhalla's.
Make sure you pull the speakers out from the back wall, and sides they will need space to breathe.
