Hello, Not an expert but a big fan of Luxman products. Excellent build quality and supper clean sounding. The silver faced units are the earlier and better gear. Cosmetically they are beautiful, simple and understated. IMO.
I have an L-5 that I bought new and have played almost daily since. However, I never knew just how good it could sound until I got my first pair of Klipsch speakers,(rf-25's)
Then I was truely impressed by how great it sounded when I added a set of Heresys.
And now I am just blown away with the sound and power since I aquired my first pair of forte II's.
