Audible Illusions M3B question

OP. You’re lucky only having to wait 6 months for the new unit. I’m glad you are happy with the unit. 

It is very sad to see this wonderful sounding product suffer due to the very poorest imaginable customer service. 

I have owned an M3A and now own an M3B. I also went through a very long wait with many ignored phone calls and many broken promises to get my M3B.

I have always used the factory tubes and in about 25 years of use between the two preamps, have lost but one single tube.

I hope my money, my wife and my M3B outlive me. If my M3B dies, I shall regrettably look elsewhere.

I certainly can understand the frustrations. My first AI M1 provided faultless service for over 15 years, with no new tube replacements needed. This new M3B sounds superb, and thus far. no issues whatsoever. Personally, I have no issue with the stepped attenuators. The unit is dead quiet. The soundstage open and clear. Diane Krall sounds like she is in the room. 

I’m pretty sure Art Ferris prioritizes Audible Illusions products to his dealer network. That could explain these prolonged delays to customers who deal directly with Audible Illusions.
