I asked the same question to Totem directly, or more specifically, if my Sim I-5 would be a good fit for the Totem Hawks & Forests. Here is the email reply:
"Both the HAWK and FOREST would be comfortable with your room size and musical preference. In terms of your amplifier, the I-5 would be better suited to the HAWK. From our personal experience we have found the I-5 to be slightly "cool" in nature. The Hawk which tends to be slightly "warm" should provide a nice balance. Although the FOREST is more demanding to drive the I-5 can still handle the load to a moderate/high level. Although it will play to satisfying levels, maximum dynamics would not be reached. We recommend you audition both units as each model is different overall, and personal taste would be the determining factor."
