Audible Illusions M3B or L3


I plan on getting one of these two. I've read a lot about the M3B but very little about the L3. Has anyone compared how these two preamps are sonically? Any difference? If you were to get one of these, which one would you get, and why?

How is the 'Gold' phono board for LO MC's (I'm using a Lyra Kleos now, in to a Fosgate Sig. External phono preamp)?

In advance thanks for your input!

I am waiting 4+ months for my L3 line stage... I hope it's worth the wait! I purchased it under the factory exchange program, giving up my excellent and trouble free 16 year old Mod 3A. If the 3A had a remote volume, I would have kept it at least another 16 years. Has anyone else had similar delivery delays recently?
Now I'm worried. I sent my m3a and a check in early February. I'm still waiting to hear from them. I'll be patient.
I like some audible IIIlusion's product's, to tell you the truth here, I am surprised they are still in bussiness after all these years!, I will also say, they do have a bad turn around on anything, however, they do last for years, a small outfit such as this has comprimises, some may believe it is worth it, if you have the patience, it is!
AI's turn around time is terrible. I purchased an L3 from them last year and waited about 4+ months for delivery and I am only 60 miles from the factory (not that it matters)

however the L3 is a great pre and worth the wait. It is very adjustable wrt gain as mentioned earlier. Just make sure you use the recommended tubes as it will eat lesser ones.
Hi Stereo5. I was reading an old thread you had with Princebaba, a director at Audible Illusions who stated a 3B Line was avalable as exchange for 3A or outright for around $1850 refurbished or also new. I live in the UK and have a 3A which I love, that said, if the 3B is better, how do I get hold of one outright? I don't use the phono stage of my 3A so the line version would be perfect. Thank you.
