I have owned the SFL1, SFL2, and currently have a Line 1. I find the SF products to sound neutral and accurate. I also have a Rogue 66lsr which souds very different. The Rogue is warmer sweeter and richer, but it is softer and less accurate. The SF is much more neutral and revealing. It depends on which flavor you like. I thought the SFL2 was richer than the Line 1 but the Line 1 is faster and more neutral.
Sonic Frontiers Preamps - Cold & thin?
In reading reviews on SF preamps, there seem to be two camps: those who think they are among the best tube units out there, & those who think they sound analytical, & thin in the midrange & treble. Would like to hear other's experiences & how they would rate them against AR & CJ. Also, how does the SFL-2 compare to the newer Line models?
