Barb, I am powering the Totem Wind with a Krell kav-400xi and it sounds great!
I would love have Totem's own Amber integrated, but as it is no longer available I'd have to wait for one to come up on the used market. The Amber was a joint venture with SimAudio. Sim stuff sounds good with Totem, but I would question if even the i-7 would have the 'uumph' needed to power the winds. I ran out of power with an i-5 on my Forests in a previous system.
