Well Big'un you certainly have outdone you're self this time !
I have had interest in upgrading for about a year now and with the development of Exotica 3's I have been waiting to see yours and the others since the prototype introduction.
You truly have a unique styled pair, the copper is one of a kind I'm sure. My vote from the first was on the 2-cabinet design, base on convenience of weight and mobility. The single cabinet is fine, depending on cost difference it still maybe the optimum choice. However when you are spending this much its best to get what you want ! I am very impressed with you're attention to detail with the associated parts of the speaker, very well done!
I guess the biggest surprise to me is the choice of the amp. I have never had the opportunity to hear the Electrocompaniet equipment but I am aware of the brands very good reputation. I will have to agree with your choice of solid state over tubes, not that the "tube sound" is inferior to Solid State, its my realization that playing with tubes would not be my game after the newness of the experience was over ( that a personal reflection knowing myself). But a significant point is when SS amps go beyond the typical designs, offering advanced technology, such as (low to none) feedback implemented to the different stages of the amp for one, puts this Solid State amp in a different league. The reported sound character of the EC AW180 mono blocks uses terms like accurate, realistic upper bass / lower midrange, excellent reproduction of acoustic music. The reproduction of Horns, Cello, wood instr. and piano are reported to be wonderful. Also the report that the amp does not give the "front Row effect", that is it doesn't force the forward feeling of being in the front row but rather puts you where the recording intends. Now I have not idea if these stated reflections of the amp sounds are typical hype or are a truthful, agreeable, nature of its sound. BUT I can't think of a better assessment where a SS amp needs improvement. This amp should go great with the stated qualities of the Exotica drivers!
Anyway sorry for the long drawnout post but I must admit I am very impress with your new system and would love to hear it.
