Line Magnetic owners...how quiet are they?

Fjn04: I too heard good things about SED Winged 34's. Is it true though that SED factory closed? I read that on tubestore.com. I know they're still available, but is that true?

The Emotiva CMX-2 will eliminate hum. Or simply changing the stock rectifier to a new production Mullard and changing the stock 12ax7s to Psvane Treasure Series mk2. Doing these things, I eliminated all hum.

I own the Line Magnetic 518IA and it is near silent. I've read about buzz but I've not experienced it.

I'm an LM dealer, and have sold quite a few of the 518's.  Not had one yet with any hum issues.

FYI-- The 518 has hum balance adjusters on it, so if you do pick up any hum, you can try and adjust it out.

The whole LM line is really pretty awesome, with the 211, 518 and the all new 508 being the most popular units for me.

Ha...just noticed that the original post is from 2014....imagine that the OP has done something by now!  lol
