The classic line would be, it sounds great!
 I think me pre part of my system is where I should upgrade.

I know this thread is a bit old, but I wanted to let you know how things are going for me and my Modulus 3B.  First, it is an amazing preamp.  With that said, AI is really dropping the ball now on things.  When I ordered my preamp I was told it would take 3 weeks.  It took 5 months.  Worth the wait, based on the quality of the sound.  Back in June of this year I decided to order a set of replacement tubes to have on hand.  It is now 9/10.  Still no tubes.  I was told when I place my order all they had to do was match them up and I would have them in a week or so.  I have called at least 20 times and get a different excuse each time.  The tubes were sent.  We are waiting on a batch of tubes.  They are matching the tubes now.  The tech that does the matching is on vacation.  The secretary is out to lunch and she will have to see if the tubes were sent.  etc, etc, etc.  AI make amazing stuff, but they are now at a point of not being able to even send out a set up tubes.  So sad, since the product is so good.  Personally I am of the opinion that the people that are in charge there have reached an age where they are just letting things slide, and since they make enough money to get by, the rest doesn't matter.  IMHO!  
Having owned 3 AI preamps including the 3B, I agree.  I believe it is a 3 person operation at most with Art Ferris (semi retired) , a tech and secretary.  I am lucky in that I never needed service.   I waited 4 months for tubes that never arrived.  I bought the 6h23neb tubes (matched) from the tube store and never had a problem and they were dead quiet.  Also, received them in 4 business days!
I just bought a L3A from Art that was a dealer demo.  He completely refurbished it to make it in as new condition.  It took a month to receive it and several phone calls,  but I honestly expected it.  I think the whole shooting match is Art, his wife and the tech. Anyway, it was a great deal and Art was responsive.  I am pleased with the L3A and M3B I own.  Musical, reliable and affordable. 
Hey dmc, how is the L3A compared to the M3B ? I hwve the vida lcr phono amp and will.only be using their line stage.

Btw, is your vanilla or black gate L3A ?

Cheers.

I just received a AI L3B line Stage PreAmp, after an unreasonable 12 week buildout. It is georgeous, inside & out. In my rig (a recapped Conrad-Johnson Premier 11a, Martin-Logan Aerius’ speakers) except for the waittime, I am very happy.
