At the Stereophile Hi-Fi show in New York, Vince Bruzzese used Totem's own "Amber" integrated amplifier to drive the Forests. Vince told me that Totem designs its speakers to sound good with a wide variety of amplification, but would sell an Amber to anyone who wanted one. I didn't ask him how much it cost, but thought I remembered seeing it priced elsewhere around 4-5K.
After Vince demoed the Forests/Amber, I stayed on to hear the Hawks driven by the Plinius 8200 Mark II (which he also used to drive the Model 1 signatures).
Fantastic sound from every model, and very hard to pick a favorite.
