Dear Orfeo,
Indeed Aries Cerat electronics and speakers take musical reproduction to another level.
I have since added an Aries Cerat Impera Signature Pre-Amp, and the Aries Cerat Ianus Essentia power amps, for an all Aries Cerat system - a real joy! (time to update the photos).
The Aries Cerat Stentor is an extremely musical speaker - this is the only pair made by Aries Cerat. As I understand it, the manufacturing cost was too high to make it a production model (its retail price should have been >euro 30,000). It is a sealed box boss design delivering fast bass, with a Raal ribbon tweeter, and a non-horn conventional midrange driver. Of course the genius of Stavros Danos is in the crossover design that delivers a live musical experience - such is the integration between the drivers. Of course the Symphonia horn speaker is at an altogether different level but also at a different price!

Enjoy your wonderful system too!
