Which is Best?

I'm ooking to buy a Pre Amp/ Phono Pre Amp for my Rega Planar3. My Amp has no Phono Stage.
I've done some reading and narrowed it down to a few :-

NAD PP2
Naim Nac 282
Musical Fidelity X-LPS
Naim Nac 112X
Linn Linto
Trichord Research Diablo
Krell KSL

Which do you think out of these are any good?

I have the X-LP2 from Musical Fidelity -- that's what I voted for with my wallet.
