I'm Assuming Rrolack is interested in sound characteristics between the three preamps. I can only give my experience with the Lamm & ARC.
I believe the Lamm gear is a more minimalist approach. The LL2 Deluxe version includes higher end capacitors. This could be the difference im hearing between the preamps
ARC chooses to include more comfort features like a remote digital readouts maybe more switching flexibility.
Each company decided to spend money in a completely opposite direction at the same price point
I piggy back a Manley Steelhead for the phono stage with the Lamm so I do gain more flexibility but at a cost.
Best way to decide is to go listen and touch each one. use the controls. You almost instinctively know which one is best suited for your needs and wants
Enjoy
