The truth is that there are plenty of good amps available. Why not let your speaker selection come first, and let that choice help you decide what amount of amplification you need to drive them without clipping?
As far as your question about choosing between a 2-channel receiver/amp or a HT receiver system... Yes there are very good quality HT receivers available in your price range. Yamaha, Denon, Onkyo, Integra, NAD are all good. They will not be a compromise in sound quality compared to a 2-channel system. You can always use an HT system in 2-channel mode, and you have the option of adding extra speakers for surround sound in the future. Most of the newer features of convenience and added connectivity will be found in HT receivers and not in dedicated 2-channel systems. If you plan on having your speakers in a different room from your other gear, you might want to use a remote control that can communicate from one room to another. It is more likely you'll find that in a modern HT receiver than in a 2-channel system. There are numerous other features in HT receivers that might be useful to you. Let others mention some.
If you really want 2-channel gear, have a look at the
Outlaw RR2150 Stereo Receiver for $650. For more money, look at products made by
Audio by Van Alstine. They are some of the best I've ever seen. I wouldn't pay any more than that.
If you like the Totem Hawks, consider the
Salk SongTowers. I have a pair, and I definetly like them much better than the Paradigm Studio 60s. Read my
listening impressions here. Jim Salk is a internet-direct speaker maker who, until the SongTowers were released last summer, specialized in expensive custom finished speakers in $3,500 and higher price range. The SongTowers are first rate and beat anything IMO in the under $2000 a pair price range. If you want to hear a pair, contact Jim Salk through his website to see which of his customers lives near you. I live in Maryland and would be glad to have to listen to them.
