Looking at the pictures of the Aries Cerat//Magico/Entreq/SMT system I can not avoid an hypothetical question concerning the darkest side of audio: how would this system sound without the Entreq's?
We didn't do the test (for the fun) with/without as it was not the purpose of the set-up. You may want to evaluate yourself in your system if your local distributor allows a home trial.
Furthermore, there was one silver minimus connected to the DAC via the unused RCA connector and finally one silver minimus was connected to the negative terminal of each speaker which almost always gives a very nice result.
I now have the Aries Cerat stack in my demo room at home without any Entreq and the sound is very nice and have no immediate urge to connect the Entreq although I know it will improve even further by putting them in.
Now, if you want a definite answer on the Aries Cerat electronics with or without the Entreq, you are more than welcome to come and listen at my room (but only from January on as I am without music from next week on).
