Mine is dead quite,.. only a touch of tube rush with your ear at the speaker and the volume wide open. No transx hum at all. I do plug into a PS Audio Power Plant though, so I know my power going in is close to perfect.
Line Magnetic owners...how quiet are they?
I have had numerous tube amps/integrateds over the years that made various levels of noise, ranging from dead quiet to significant buz/hum that can be heard several feet away in the listening chair. I'd like to know how Line Magnetic owners would rate their's. I'm talking about any hum/noise coming from the amp itself, and I'm particularly interested in the 518.
