DVD by Oppo 205


Will the 205 provide a better experience for DVD viewing than an older high quality video player’s  upconversion via HDMI?

Glad you mentioned vocals !  I am an opera nut. Love audio and video. I have a glass of French Brandy and - honestly - I am there. I am “supremely” grateful for DVD’s and enhancements are Gravy !!!
The UDP-205 can upscale, but may not, depending on how you set the output resolution (setting). 
You would have to decide what’s more important.  Your original question was for DVD 480i video quality.  The older 105D is better because it has Darbee processing for low res.  The newer 205 has better audio quality if you use the analog outputs, but will not be as sharp on the low res DVD video (since it lacks Darbee).
Thanks again guys. With auxinput comments re the video and Darbee I found out the 205 has a completely new video chip they partnered with a video chipmaker to jointly design. I hear so much good about Oppo I have to assume the new chip will outperform the previous. And I assume Darbee will bring out an improved stand-alone fairly soon which may be used with the 205 if reviews are positive. So I have decided on the 205 if I upgrade now. I appreciate the new videos made in 4K will be much better than upconverted DVD’s however I have a huge selection in DVDs that I enjoy in 1080i from HDMI and all the positive comments indicate there’ll be a noticeable benefit with the 205. I appreciate your inputs very much. 
I had a similar question regarding plain old Blu-Ray and the rep at OPPO told me that if all I wanted to do is view Blu-Ray and not any 4K content, then I should stick with my 103 and not bother with the 203 or 205 as there wouldn't be any improvement. If you have any further doubts. give them a call as they are quite honest about their gear.

All the best,
