this is a very interesting debate and I would like to address a few points:
1. Regarding lacking SDI/HD-SDI and RGBHV in- and outputs: Lumagen is a highly priced product compared to even the top end DVDO units and as far as street prices go might even be more expensive than the Crystalio offerings so it will always be compared to these that have both this connection options. Lumagen also does keep their products up to date longer and has a history of providing at least an option for SDI inputs and analog outputs with their lesser processors that is now gone for their highest priced processor - makes no sense to me. So the Radiance will always be compared to both older Lumagen units and to the other two manufacturers' products and it it the only processor in this little niche market not to offer said functionality, not even as an upgrade. Bad decision imo and I have said that from the start. I know about a dozen CRT people who now have DVDO and Crystalio because of the combined SDI/RGBHV issues and I think that many would have gone with the Radiance if it had offered said connections, but of course I am talking about a nice within a niche
2. Players with unmolested HDMI output: The new Pioneer players have a source direct mode that looks very nice and that can be set to have zero ringing and very nice color decoding from my tests, they can also be set to output only 422 - tested with the Pioneer 51 FD. No problems outputting whatever is on the disc including 576i and 480i. There is also an HD-SDI mod available for this one but I live in Europe and have to pay about triple for a player that has that implemented comparing to what I have to pay for a normal unit - too bad or I might be inclined to test HD-SDI vs HDMI. To sum things up: To my knowledge the Pioneer players are the first players to offer such a source direct mode for HDMI that is implemented correctly and they should be commended for it, how about trying one out Glimmie ?
3. Glimmie is right that there are issues with analog inputs to the Lumagen, I am currently using my Radiance with a Holo 3D card because of it. I have contacted Lumagen about this issue but not heard back from them with regard to doing something about this, maybe I am the only one to complain ? In a nutshell the analog inputs seriously underperformed in my tests with SD inputs and seem to have too much, not too little filtering which affects fine detail and gives the image a soft and at the same time processed look, not very nice. Ringing was not really what I thought to be the biggest problem with this though, it was the pastyness and lack of detail in the picture that seemed so wrong that I now use the Holo card and feed the Radiance a 576p pr
480p signal from it, the Radiance then does the upscaling and also adjusts for shifted chroma with the Holo. In my tests I have compared the Radiance against a few other solutions with an higher end Muse LD-Player with normal LD's (don't laugh, what else would I want to feed analog, as Glimmie still did not mod my LD-Player to digital output
) and broadcast TV and the other solutions all had certain advantages over the Radiance.
The HDMI inputs do not have these issues though and I guess that is why most users do not complain much, the Radiance is indeed very powerful with HDMI sources, as soon as it is fed digital most is well, just don't use analog if you want an unmolested signal- there is no option for this (yet).
4. The scaling via HDMI for 480/576i and p sources is second to none with the Radiance and outshines all other offerings I have tested including the VP50 - no doubt about it and one of the reasons I use the Radiance.
As I said I currently use the Radiance with a Holo 3D PC attached for analog sources - it is the best out of both worlds for me at the moment
