I ran my VP100/150 parallel with my Denon 1804 and had no problems. \:\) My reason for the VP150/100 was simple curiosity and I purchased the VP150 just to see what the differencs were between the 2 and found it to be very minor. The VP150 does play ever so slightly lower and I have found deep male voices sound better through it, but I only noticed the difference because I was able to A/B compare; other then that really no differences.
