For upscaling standard definition sources to 720p or 1080i, anything much better than the Faroudja as in a Crystalio 2300 ? I'm using an analog Sony HDTV ... I read here for a few days and saw Silicon Optics, but opinions seem to differ and didn't find specifics as to what aspects are better even when claimed to be ...

The Lumagen video processors have Lumagen's proprietary "no-ring" scaling. This "no-ring" scaling will give you the least artifacts on the edges of objects when you scale SD video sources to a HD display.

According to their website the only product that has their " no ring" scaling retails for $4495.(The Radiance XD)
None of the other products are listed as having "Proprietary Lumagen no-ring scaling"

All of the Lumagen products have the proprietary "no-ring" scaling.

in my 3 years with the Crystalio 2300 I do not recall seeing any rings, either from my Sony HS51/ Shap 10000projector (doing 100" sizes) or Sony 36" CRT HDTV

All of the Lumagen products have the proprietary "no-ring" scaling.

If all their scalers have this then they need to change their website since the lack of this information can affect potential customers.

thanks for the responses already !

I thought the biggest problem I experience is whenever upscaling to higher resolutions than 480p, the sharpness and contrast degrades too much, losing 3 D depth and sharpness, all in the name of upscaling, I hope some newer scaler can solve it

I'm running 480i or 480p mostly ...
