I've been meaning to do a Hawk vs. Forest "test" at my house, as I know of a guy near me who owns some Forests. I love my Hawks, and they provide an AMAZING full range sound when driven by my 100 wpc Audio Research VS110. In our last home I had more volume to fill and they were able to mate PERFECTLY with a Lightning sub. Since moving, the Lightning has moved into our family room to sit beside a set of Rainmakers in the Home Theatre.
Which reminds me, the Rainmakers are another Totem jewel. I also own some Spendor S3/5se's (up for sale here so maybe I shouldn't say this) and the Rainmakers walk all over them. More rhythm, more body, more extension, you name it. They absolutely disappear in the room no matter where they are.
Another Totem revelation comes with the beaks. I was skeptical, but bought some anyway. I loved them so much I bought another pair. The second set doesn't add as much as the first, but it is still an improvement.
As far as cables go, I've a/b'ed the Sinew against Chord Chorus/Anthem/Singature, Audioquest Diamonback/King Cobra/Jaguar and even some Acoustic Zen Silver Reference. The only one to really compete was the AZ at nearly three times the price. The rest of my system is now Sinewed.
I'm torn right now whether to upgrade my preamp or put the Urth power cables in place. I'm a real believer in Vince and his team of magicians.
I can't say yet whether the Hawk is better or worse than the Forests, but I can say that the Hawk is an awesome speaker in its own right.
