Hold the phones... I think I found what I was looking for.
Yamaha DVD-S1800, currently being sold for ~$90 on amazon:

After much reading on the forums, I have made the following conclusions, all based on my own set-up. Since my Yamaha RX-V2600 has HDMI 1.1 and cannot do DSD over HDMI, I have to utilize the DAC in the player and discrete multi-channel analog in/out. As I said, I don't really care about video, just audio, so I am most biased toward the quality of the analog outs in the player.
There is much praise for the Oppo players, and that praise is echoed throughout the net, with a few contrarians saying that their audio DACs aren't their strongest suit, which doesn't matter if you simply pass digital audio over HDMI. In my case, that isn't the option. Pioneer Elite players, like DV-(48/49)AV get nice reviews, but they are still around $180.
The Denons, like 1930, 1940, 2200, and 2900, are nice options, but folks say that they aren't truly Denon quality since they are at the lowest end of their spectrum.
The Yamaha DVD-S1800 seems like a perfect match to my receiver - it appears that the DACs might even be the same or close to what RX-V2600 has. I appreciate also that this player seems to emphasize pure audio listening, somewhat like Denon. Oppo seems like a great *all-around* unit to me, especially for folks whose receivers accept DSD over HDMI, but it's quite pricey for a used value player. So for $90 brand new (incl shipping) and my definite attraction to Yamaha, I can't see how this option can be beat for my purposes.
So far, I feel very much at peace with this decision and happy to not have to agonize over choosing a player any more. Not an easy decision!! LOL.
As always, thanks to everyone who contributed thoughts and comments.
