Marvey compared the Luxman to EC's Zana Deux, even though he seems to not have tried EC's own solid state Black Widow amp.
I find the choice between the Black Widow and the ZDS difficult. I would probably lean towards towards the ZDS, but the heat from those Russian tubes just wouldn't work during summer up here. I have a speaker amp with 4 of them so I know. So the BW is the most logical choice. At some point I will add the Gumby and may just spend time listening to more music. Of course I could go nuts and have both amps. One for summer the other for winter. But that would be a bit over the top. Although the nice warm glow from a tube amp on a cold winter night.........
Because when the comparison by Marv in the OP was written, Black Widow didn't even exist (even the name, the prototype was called Red Top).
Marv has said that the Black Widow was "so good" that they looked at the Zana Deux SE again...thus, the newer "Zana Deux Super."Whether it was that or Marv's curiosity & ever-modding spirit that resulted in ZDS? We may never know.
I have been extremely happy with my Oppo HA-1. It does everything I need and then some, for a bargain price. Highly recommended.
