In my home theater setup I have 803n mains and 805n surrounds and the big center channel speaker that I always confuse the initials for. I gotta tell you the 805n speakers are magical. I love them. I have another pair I use for computer speakers. I tried the later models with the diamond tweeters but they make my ears bleed.
I am running Wilson Yvettes in my main system that I bought for half price. I love them completely. The Sabrina is their new lower cost model that I saw for sale on Audiogon yesterday. Some guy has a virtually new pair with two sets of grills, one dark and one light and he is asking half price for them. Oh my, I can imagine a use for them and at the price he’s asking I should jump.
There are so many possibilities for you, endless possibilities. I just want to remind you that what you have right now is pretty damned good. Especially with the S3. Maybe a second S3 sub would be a smart place to put your money. You don’t want to be one of those guys who buys something new every week. (like me)
