Got my PB2+ on Friday. I barely left the house all weekend. I am listening to all my music again, for the first time it seems, discovering things I've never heard before. I'm renting a lot of LFE movies, hearing and feeling things I've never sensed before. Das Boot. Whoa... I'm rattling things I never thought would rattle before. A problem I'm now happy to work through. I'm giving Avia a good workout. My SPL meter may need a new battery soon. My sub purchase was just one small step for SVS, but my giant leap in the HT/Audiophile experience. And I have entered the realm of which there can be no return... Props to SVS! A wonderful product.
