Yeah Mojo, i am reading through the other posts on the 600s. As tempting as the more subs proposition is, I think i will take a rain check on more subs at this time smile smile The 800s are giving me enough levitation at this point. It is just a couple of weeks since i got all this gear. And there is enough for me to experiment with and keep me engaged for a little while. And it is too early to convince wife and family to get more stuff and seek Nirvana! smile
