Two completely differentsounds. The X-1 is very neutral and dynamic but not really a warm sounding preamp. The SF has the tube qualities but will loose a little bass slam compared to the Pass IMHO.
sonic frontiers line-3 vs pass labs x-1
I just replaced my fpb-200 with a Pass X-350(my god what an improvement). I currently have it mated to a line-3 with amperex 7308's in the output and Dunlavy 4a's. Source is a EMC-1 mk2. I was intrested to know if anyone has had experience with both of these preamps in a similiar system. I would like to hear the x-1 but dont know if its worth going to the trouble of selling the line-3.Thanks.
