The focus of my system has always been to achieve decays and harmonic structures. Sacrificing things like the ultimate in resolution and bass extension were done to get the 3D magic.
That's the shizzle and what's missing from most digital...
So I'm not sure what it is about my system that makes the NU significantly outperform the Sylvania. But in my system, relative to the NU, the Sylvania is horribly flat and way too distant. Had I only had the Sylvania and this was used in a multi-DAC shoot out, I doubt I would end up picking the L6 as a top-performer relative to it's competition.
Very good point. I am certain Lampi's get dumped by folks who do not do their due diligence. A common theme in audio....:/
