30 foot long Balanced Cables to Balanced/RCA Adapters into Amp's Stereo RCA inputs?

I just bought Blu-Ray player: Oppo BDP-105, arrives in a few days.

 Primarily for it's 2 channel audio quality. 

It just occurred to me, I could use all of it's audio, video, future streaming features if I:

1. Locate it in the small Home Theater system

2. HDMI to AVR of Home Theater, and

3. Balanced Outputs (audio only): 30 feet to the 2 channel amp in main music system (far end of the same room), use balanced/rca adapters at the amps rca in jacks.

then I could always access/see the menu for audio setup, and use all of it's capabilities

I've never used Balanced Cables.

Advice? Concerns? Avoid doing this!!!

I could buy 50 ft cable for more slack both ends: any reason to keep it to 30 ft?

thanks for any help,

There is nothing wrong with using balanced cables. 

Do you really need 30-50ft? Shorter runs are always better if you can - 10 ft and under for the lowest possible cable resistance.

Regarding jacks on any system, lighter cables with a solid fit are ideal. You don't want a very heavy cable. Some premium (very expensive) cables may be much heavier...

I would not use unbalanced runs for such a long distance, which is what you'd end up with if you used simple passive XLR to RCA adapters at one end. You're very likely to pick up a lot of audible interference.

You could use a transformer-coupled adapter, but that will affect the sound to some degree. Whether or not it is audible would depend on you and your system.

Alternatively you could use an active converter, which also runs the risk of having an audible impact on the sound depending on the converter.

Also, even for a shorter distance, you would need to know what the right internal wiring should be for your XLR to RCA adapters, unless you're using a transformer-coupled adapter or active conversion. You may need to ask OPPO or find someone else who knows the right configuration.
