Oppo/something else as a Processor

It will be  very tough to find a brand  new universal player that  has the five analog jacks. Even the  new Pioneer Elite UDP-LX500 does not have them. The selling prices for Oppp 205's is now in the thousand of dollars on the secondary  sites so that is getting  crazy.

Yamaha makes sort of a "universal player", the Yamaha AVENTAGE BD-A1060. It does not play DVD-A but does have balanced XLR connections, but only one HDMI output. It is under $500.

Denon has a similar prices unit as well, but no balanced XLR connections... DBT-1713UD . 

I first had a  BDP -95 and then upgraded to a  gently used BPD-105, which I  got for $700 here. Many other posters have listed companies that will refurbish and supercharge your Oppo player.

It is on my bucket list to do that to my 105.

Folks have recommended this site as they do a tube modification.

Here is another one.

There are a couple others sites, which I did not  bookmark, so maybe other members can  post the links.

I use a 105D as a processor, and like you I've looked for an alternative, mostly because I'm looking ahead to 4K and don't want to pay the current prices for a 205.  I've found nothing - there doesn't seem to be a contemporary equivalent.  Not sure what I'll do when the time comes. 

You might look for a used 105, 105D, or 205.  The Oppo designations that end in 5 have audio processing superior to those that end in 3, although the video is the same.  

I've been using my 205 directly to a 300-watt NAD M22 Class D amp to drive KEF LS50s with excellent result.  In the process of downsizing I discovered I have a 95, 105, and 105D in addition to the 205.
