The arc ls2 only has one tube and yes it was fairly new and a big improvement over the old one.
i tried both dig inputs through the cd player and through the c48 but stuck with the c48 as just about every input whether digital, rca or balanced sounded very very similar, whereas there was a noticeable difference on the older arc depending on whether rca or balanced input.
Not saying the c48 is the last word in sound but for me with the convenience of the digital inputs(5 in total) two sets of xlr ins and rca inputs, plus mm and mc phono inputs and a headphone out...and a remote that also controls my mvp851....
well just a lot of convenience factors that were also very hard to ignore there!
