Looking for help with a Benz SL low output cartridge

so much for me to digest. I currently use a Lamm 2.1 deluxe pre. I don't know the gain. I too, don't think I have enough gain on the KC Vibe. Upscale Audio is who suggested the SUT. Coincidently I have a friend who just listened to a Bob's device and he acknowledged quite an improvement. I am waiting to hear from Ron. I will look into other options mentioned above. Sorry I can't get them all individually.

thanks

The gain on the Lamm is 18db. Add that to the gain on the phono stage!

@dpm2340 

cartridge is 0.4 mV signal, 12 ohm coil, correct?

Gain settings: 40, 45, 50, 55 or 60 dB
Loading: 100, 200, 475, 1k or 47kOhms

have you changed the jumpers inside the unit to:

gain 60 db (max signal boost)

loading 100. (you could also try 200, but start with 100)

after those changes: NOT ENOUGH VOLUME?

"The LL2.1 is a direct replacement for the LL2. Aside from a few new parts and slight changes in the schematic, the most important modification, at least from my perspective, is the introduction of a switch-selectable 15dB gain attenuator. With this switch on, the gain drops from about 18dB to only 3dB."

double check the attenuator is not engaged, so you get the 18 db gain, not only 3 db

FYI…when I had the Vibe Mk2 with Hana ML which is identical to benz sl specs wise,  I complained about low gain. It didn’t feel like it was enough at 60db. The presentation lacked in drive and dynamics. 
Switching to 20/20 Mk2 addressed this issue. I know the overall gain of the system needs to be taken into account, but the Vibe behaves like it does. 
Adding a SUT might help but the point I was trying to make before with going down the phono stage upgrade path is probably the best approach in case of the Vibe. 

I’ll add that as nice as 20/20 is, the overall sound signature remains mellow, sweet and polite. Much better than the vibe. But if you’re looking for explosive dynamics and impact, probably worth exploring other options
