No. They're mid tier for SVS. The thing is, their mid tier blows away top of the line subs from many speaker manufacturers (including Polk, IMO). I really do think either one of those 2 will knock your socks off. Even their entry level are fantastic.
I love, LOVE my SVS Ultra Bookshelf speakers. For the price, they're very good. What I did was keep an eye on their outlet and waited for a couple to show up with very minor marks on them.
Like this one here for $399. You can see from the pics just how minor those scratches are. They show up in black piano gloss at that price fairly often too. They have
this one there right now with no damage for $449. They have Ultra Towers too, but they don't show up in the outlet very often.
I've been told that they have one of the best dome tweeters out there right now. I was also told that if I want to upgrade a Raal (ribbon) tweeter would be the only thing to best it. If you're considering the SVS' speakers the Ultra line is an excellent choice in the price range.
