has anyone heard the new levinson 53?

article states the 33h holds its own against the newer amp,
but doesn't "look sleek and modern". so what does "holds its own" mean exactly? the newer amp is much more powerful, so in that respect alone there is little basis for comparison. better to haul out the #33's and see how they compare imho.

I heard that the Levinson 53 is built around a proprietary class D switching module and a linear power supply. I hope to hear it at RMAF in October. G.
