Micah, i have Krell amps and I am not sure if i want to run those 2 speakers in parallel.. I don't think that there are any recievers that could power a pv150- and vp180 in parallel safely.. If you have a power amp you might be able to get away with it, but you will need a pretty strong amp... my amp's are rated at 250W at 8ohms, and 500W at 4 ohms.. and if i put a 2 ohm load they would be making 1000W, but Krell has not designed them to be stable at 2 ohms though, so i don't know that i want to push them....
