Current model DVD with 5.1 / 7.1 analog out - "Oppo Like" features

Hi,
My Oppo 103 has developed a problem during audio playback and I think it's time for retirement.

My challenge is that I use the Oppo as a surround Preamp to create a crude 5.1 system.

HDMI signal feeds Oppo HDMI IN,  Oppo HDMI OUT goes to TV, Front channels got to my 2 channel rig and rear channels get fed to an older amp.  Then I use the Oppo settings to try to match the rear levels to the front and get a quasi surround sound.

So, I use the Oppo not only as a player, but also as a preamp along with it's various settings to create the 5.1 surround.

A cursory review of the Forum suggests that this particular group of features is not easy to come by and that if I want this setup I might have to find a used Oppo.

Do I have other reasonably priced options (less than $1,500)?  I don't need the streaming features of the Oppo as I have a Lumin D2 for that, but I would like to find a way to retain my crude surround setup if I can.

Thanks,
Phil
