Not true at all. With the right tube it will sound very euphonic.
I'm very interested in the LG. However, I'm not a tube-roller, per se, mainly because I haven't had the opportunity. I realize the LG is suppose to reflect the sound of the selected tube, but at the end of the day, it's still a hybrid amp, right? Is it correct to assume that regardless of the tube, the LG can't be made to sound like a "tubey" amp (let's say the Woo WA22), right?
