Totem Forest, Zu Soul, or Superfly

Have never heard a Totem, but at 87 db sensitivity, it's not very efficient at all and is likely a poor match for a 15 watt amplifier, monoblocks or otherwise.

I think the Soul (I have the Superfly) is quite special and would sing with 15 watts.

Having read through the threads myself when I was considering my first Zu purchase, I noted that many who said that the Zu sound made them run from the room had listened in convention / show conditions. As I understand, the Zu speakers have rarely auditioned well at industry shows.

The Zu house sound is fast, alive, coherent, musical. If you say where you live, it may be possible to find a Zu owner near you who would be willing to have you come by for an audition.

Personally, I think you will be delighted with a pair of Soul Superfly, and $1400 is a terrific price.
