Welcome to the world of paralysis by analysis!
I have the infinity 362's along with the 350 center and 152 surrounds.
I own my home so I have a picture knocker off the wall,SVS cylindrical sub.
I purchased all from responses on this forum and have been very satisfied.
I auditioned speakers up into the 3000.00 dollar range and was hard pressed to hear MAJOR differences in sound although I really liked the PSB,s.
But being the cheapskate I am,Infinities were my choice.
They tend to be a tad bright but you can tweak with your equalizer.
Beware,they are top heavy and can be tipped easily(don't ask me how I know)
If you go without the sub,get the 162's as you will benefit from a tad more bass.
You can improve your 363's and center with some modifications provided by a banned member,do a search or ask Alex,I believe he had modified his.
For the price you aren't going to find a better speaker,they have excellent drivers.
My wife hates the system,that was my tipoff that it sounded good
She claims her coffee has sound rings in it when I watch War of the Worlds.
