NHT’s C Series is better than SVS for speakers, so the C3 or C4 depending if you want bookshelves or towers, and then the matching C LCR as a center.
SVS is good for the money for subs, but HSU and Rythmik are great for the money.
A/V processors cost a lot of money, it’s best to just get an A/V receiver that has pre-outs, then add whatever amps you want. The Denon X3400 is $600 new (normally $800, but the X3500 just came out, and if mainly only adds a phono, so save the $200). For power amps, the 3ch Monolith power amp is excellent, read the Audioholics review (the amp has been revised since the review, such as adding XLR, so maybe performance is even a bit better now).
