Acoustic Zen Adiago vs. ATC SCM40

Any thoughts on these speakers? Neither are sold in my town and I am desperate for input. Adiago are glowing reviewed everywhere and the ATC are well regarded as well. I have a smallish listening room (12x15) with tube pre-amp/amp. Listen to all kinds of music. Also considering the Harbeth SHL5 but they considerably more money and they would have to be twice as good to buy.
Im loving my adagios also.The more i put into my system(upgrades,room cond,ect)the better it gets.I just dont have any desire to move from them.I will say that they are probably not" unbeatable",but sound dam good.Just wont go back to bookshelf when the whole (Almost)range can be had.Had dynaudios,totem forests,kef,among others.I do listen to jazz mainly,john hyatt,van d'man,ect.I am also curious about atc's ,never had a pair.Lots a great reveiws as well.Just very satisfied with the adagio.....something every bodys just got to try insystem before you can asses a honest judgment though.
The Adiago's might be a better fit for you becasue they're front ported. I had mine about 30" out from the back wall and they were amazing. From what I've read, the Harbeth's need a lot of space between them and the back wall.
Two very different speakers. Adagios need power...they are not very efficient (87db I think). I own a pair and have used everything from 7 watt chip amps, tube amps, to 500 watt SS amps. All sound great. Great base and a very sweet highs.
