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 have an M3A with the gold phono boards. I use a Denon DL103 with the ruby cantilever retip from Soundsmith. Sounds great to me. I do not know if the circuit differs at all in the M3B.
Rnm4...besides the phono Gold boards sounding "great", how quiet is the phono section.
Very quiet, however it is tube based so depending on your speakers you may hear a faint tube noise with your ear to the speaker. Likewise I use a Denon 103r low output MC cartridge.
I have a Modulus 3A with Gold phono board. The gold phono board is all fet designed by John Curl and is very similar to the sound of the Vendetta phono preamp. The Gold phono board adds about 20db of gain to the signal, then it passes through the M3B tube phono preamp. I use it with a ZU/Denon DL103. The sound is to die for.

I also have a Modulus 3B in my main system and the sound of the 3B is light years ahead of the 3A. It is much quieter, has greater bandwidth and the sound is much more relaxed and analog sounding. I am using a Dynavector 20xl low output mc cartridge on this preamp with a Denon AU320 step up transformer. I must say that the gold phono board on my Modulus3A sounds better than using the Denon SUT. The tube phono preamp on both units are very satisfactory. Both phono preamps are very quiet using the Ultra low noise 6h23neb tubes from Audible Illusions. I have to put the preamp volume 3/4 of the way up before I hear even the slightest amount of hiss with my 89db efficient speakers.

The L3 is just the line portion of the M3B preamp, it only uses 2 tubes instead of 4. Everything else is the same. If you do not have a turntable, get the L3 instead.
Stereo5, are the volume attenuators on the 3B similar to the 3A? Same amount of steps. Same level of attenuation as in can you get past 9 o'clock?
