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.

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.
Just my personal opinion and experience, the zen, scm40 and shl5 are too big for your room.
Since you are using tube amps, if they are less than 100w, the scm40 is out of the pix. these speakers need a lot of s/s power.
for your room, its probably better you go with the harbeth c7es3 or the P3esrs.
if you go to the atc route which are also very good speakers, the scm11 would be a better choice but you'd probably have to upgrade your amps.
good luck.
