If you can find one get Lamm Industries LL2. It is the 2nd best preamp out there. Period. Lamm L1 is the best pre out there. I have owned most the so called recommended exotic preamps and until recently I never knew how compromised they are compared to the Lamms. If you still want to stay with your picks, choose the Bat. It is sonically superior and more neutral than the SF units. The SF units are good if you have a forward or bright sounding system they are musical but definitely honey colored.
