Unfortunately customer service at AI has been very poor in the past. I had to wait around 7 months for my Modulus to be fixed. Only problem was a bad soldering job on one of the RCA inputs. Plainly seen once the cover was open. I am not alone in a long line of dissatisfied customers. My dealer was so upset by multiple service problems, he later dropped the AI. But the preamp is very good value for the money, I admit.
