Sonic Frontier or Modwright 9.0SE for Aragon Amp

I am looking to get more details on my current system, which consist of Aragon 8008BB, Aurum Pream, and Logan SL3. After some research on what will give me better synergy with my current amp, I have narrowed it down to two amps;

1. Bryston BP25
2. Sonic Frontiers SFL-1 Preamp

I am kinda leaning towards the Sonic Frontiers pream simply because it is also a tube preamp. But lately I have been reading about the Modwright SWL 9.0 Signature...

While there seems to be a good synergy between the Aragon and the SFL-1, I am however uncertain of how the Modwright preamp will mate with my amp, and hence my reason for seeking your opinion.

And no, I have no option for demoing any of the gears; I am in Dar es salaam, Tanzania!

Thanks in advance
