David,
Our Weiss combo (the newer version like yours with single 176/192khz inputs) sounds a lot more complete, musical and real with a quality pre-amp, as does the Eso and the Wadia.
Have you heard the new Decoding computer and separate dac's at all, it is very good, not sure about the pricing though.
Anyway, your findings I suspect will be different, we are not restricted to just one or two pieces of equipment in turn.
However it does not stop the fun of finding out and meeting up with like minded folk!
Shrink,
The Marantz is the same unit, it is big and heavy though dig a little deeper and its not quite there.
A good player though, we have a trade unit currently, great for the Living voice obx appreciation society, a good match helps smooth out the cabinet colorations and interesting bass characteristics. really does make a good combo.
If your in the market for a £5K player, should be on your audition list
