Down to 3 choices - opinions requested

If you go Sonic Frontiers try and get a Signature model. It's worth the few extra bucks.

i think if you got any of these it would be the weak link in your system. If i were you I would get a sonic frontiers line 2, and if you wanted to upgrade down the line partsconnexion has a SE+ mod for standard line 2s which brings it into the reference realm

Forget all of these and get Modwright's SWL 9.0SE preamp for $2200.00 new, you won't regret it..

A used Audible Illusions Modulus 3A or a VTL 2.5 would be better than any of the ones listed.

You gotta love it right - you've narrowed your choice to three pieces, ask your esteemed colleagues for a ranking of the pieces that you've agonized over, and get told to consider something else.
Maybe he has a reason he wants to consider these pieces like features, price, asthetics, availability, resale, brand loyalty, personal preference, or maybe something more obscure, and would like a ranking of the three he's decided on - just like he asks.
It could happen, no?
I'd say the SFL-1.
