SGR,
You seem to like the Levinson sound. I do not know what you currently have for a digtal front end, but as far as amplifiers go if you have a chance to swap 4 levinson 436's for the 33's then I would do it. I have owned 436's 33H's and currently 33's and I can say without reservation that the 33 series of amplifiers are head and shoulders better than the 400 series amps. Before doing so I would call Levinson for a service history of the 33's.
