I owned an Audible Illusions 3A many years ago and many, many preamps ago. I currently own the Modwright SWL9.0SE Signature. It's one of the best preamps I've ever owned or heard. I have never missed the AI 3A, not even once...if that helps you any?
Audible Illusions 3A or Modwright SWL9.0Signature?
These two pre-amps are too close to call. Both have received excellent reviews. However, from the aspect of dynamics, accuracy and especially MUSICALITY, which pre-amp might have the edge???.... Also, though it is almost twice as expensive as the above units, how does the Rowland's Concerto pre-amp rate?? There are hardly any reviews of the unit.
