I am using the Simaudio LP 5.3, and am very happy with it. Plenty of gain and loading options to match any cartridge, and the sound is very big and open with excellent width and depth of soundstage. The details are there and more importantly the musical impact is there. Haven't heard many options though, so don't know how it compares to the other options in your list.
