Best Standard Def DVD Player under $8,000 used?


I am looking for the best possible Standard Def DVD player
that is BLACK. I have a Krell DVD Showcase now and it's
great but I am wondering if there is better to be had for
under $8,000 used.

I would like to hear opinions/comparisons of the video
quality for:

Krell DVD Standard
Linn Unidisk 1.1
Meridian G98
Denon 5910CI

Thanks

These days I use the Olive 06HD as a streamer which outperforms almost any highend cd layer with ease. And I use the Onkyo BD-SD809 for bluray. This player has a clocklink and is the only player till 1000 dollar which can give a deep and wide stage. Was better in timing than my 800. 800 had more weight but was not that good as the 809 in all the layers of the low freq. The 800 had a better musical sound. But the high freq was better with the 809 as well. By using the clocklink of the 809 the stage is deeper and wider than my old 800.
Connect the 809 with a Audioquest hdmi coffee or even better with the Audioquest Diamond and you will outperform many cd player till 5000 dollar. I did many blind test with clients with very expensive players. They all bought the 809 with coffee or Diamond. They sold there source. At the end they had superior sound and some had even even extra money to do other things. Reinvesting by selling old audio is what i do a lot these days. I compare sources, amps, cables with the source. cables or even amps what they own. I sell them new better stuff for good prices. And I help them to sell there old stuff for good prices. I do this Always for free, for all my clients. I write and place there advertisements. I do the eamils and send them to my clients. Many shops ask money for this overhere, I do not want to earn 2 times money on a client.
