sonicfrontiers pre-amps reliable or not?

I have had Line One for over three years with no probs. SF builds with premium brand name parts which adds to reliablility.

Has anyone compared the SF pres to the ARC´s? I have auditioned the ARC LS16 but so far I have not had the chance to listen to the SF gear. I have a McCormack DNA-1 dlx/ Maggie 3.6 combo. Your input would be greatly appreciated.

sfl-1 for 8 years. no problems

I've been using a Line 3 for about a year. I did have problems with it, but there were due specifically due to the presence of the PS Audio 300 power plant in my system (sometimes there was a significant hum from the Line power supply and it blew a fuse in my Line power supply once). When I got SF on the phone it was the first question they asked me - 'got a PS 300?'. Apparently this is a common problem. However, I blame PS Audio and not SF. Without the powerplant, it performs flawlessly. I'm very happy with the Line 3. Also, their tech support was eager to help - great support. I sent them an e-mail and their technition phoned me five minutes later to help out. One thing I'd mention, if you're looking for a balanced preamp, you may want to check out BAT as well. Best of luck.
John.
