The Audible Illusions Modulus L1 (this is the one I own) is identical to the line stage sonics of the Modulus 3A, minus the fact the Modulus L1 does not have a phono section. It was mentioned above that Audible Illusions preamps eat tubes. I think this is because the tubes are constantly on even when the preamp power switch is turned off. This no doubt contributes to excellent sonics from the get-go.
I like my Audible Illusions pre a great deal and I'm just now getting around to tube swapping. I read that Audio Research makes tube rings for the 6922 tubes. Stereophile mentioned the use of these rings do not produce suttle improvements but major differences in most all areas of the Audible Illusions preamp.
Elevick the newer AI units use two gain controls (one per channel) and one master volume. This is very handy when it comes to setting the proper gain for your particular amp. Once set you only need to adjust the one volume control from there on.
