I think all this is rather silly. Just answer the man's question:
"I'm really curious why you would consider a timestep vs a kab power supply?"
Well isnt the simple answer that the Timestep replaces and upgrades more than the KAB does and takes it a step further? As I understand it (and correct me if I'm wrong Dave) the Timestep upgrades the regulator section too which the KAB doesn't, and the general consensus is that this is sonically significant. Down to simple engineering isn't it?
It's still OK to prefer and buy the KAB one but better to do so fully informed.
Back to the main topic: I've only ever owned one other turntable, a JH belt drive which my father passed down to me when he bought a Technics SL 120. 
My Technics SL 1200 with JH unipivot arm, AT 33PTG cartridge and stripped of the crude rubber and Pocan base, soundly beats the JH belter, even more so with the Technics platter constrained layer damped. (In its heyday the JH was considered by some to be the equal of the Linn LP12 sonically.)
Technics SL 1200-MK2 (3M foil damped platter and Pocan and rubber removed naked plinth); JH Formula IV unipivot arm with magnesium headshell; AT 33PTG cartridge; home built KEF transmission line speakers; Pioneer A400 amp seperated into pre/power used as preamp into Rotel RB-980BX power amp; Tascam CD-RW4U CD player/burner.
