New speakers

Short list:
On the search for new (or used)speakers...

Room is 9x15-ish... equipment on long wall...

Current setup"

Sugden A48b
Rotel RCD 971
NHT 1.5
Energy ESW-V8 sub

Wish to replace the NHT's with a mor open sounding speaker. The NHT's sound closed in and a bit veiled in the midrange. Further, the treble is somewhat extended, but harsh and biting (i love extended treble, but not at the cost of harshness. My girlfriend can't STAND the treble).
Bass won't be an issue as I have the Energy sub dialed into the room quite nicely and will be keeping it.

Current short list:

Totem Arro
Totem Staff
Totem Hawks
StudioLab Reference 1
Epos M12.2 (NOT M12i)
Epos M15.2
Audio Physic Yara II classic
GMA Europa
Quad 12L

anyone chime in w/ what might work? I listen to everything under the sun and do not want to be restricted to 'audiophile recordings only'.

Thanks for any input.
