The LM 518IA is dead quiet and absolutely no noise from the speakers. One of the quietest amps I've ever owned. Transformers are silent too. Mine is new and still breaking in but very very nice indeed with an incredible balance across the spectrum.
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.
