Totem model 1 vs Totem model 1 Signatures

I have listened to a pair of Totem model 1 speaker and they are very good ,but are the Totem model 1 Signatures a good improvement for the money or would it be better to buy a pair of B&W 805 Nautilic speaker ? I will be driving them with a Classe CA101.
the classe would mate nicely with either totem 1....the signature is ever so slightly more detailed. the 805 would compete with either, but i think the totem is tonally on the money.
