i recently sold my 306/200 and purchased a Wadia 861se. The Wadia has the GNSC Reference Level mods. Even without the mods, the Wadia was way ahead of the Cary in every way. The Wadia is also more than twice the Cary's price.
I like the 306/200, it was a great machine for the price. The Wadia is simply a better player in every way.
