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

I put this under 'cables', and am repeating it here because I always get good help here.

...........................................


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,

Elliott

what choice would you have made, 22 awg or 16 awg?
The balanced cables we use typically have 20ga conductors. Over 50 feet and the impedances usually used in balanced lines the difference in DCR wouldn't amount to anything.

% of purity between Pure and OFC is very slight
Actually if they are being honest there isn't any at all. 'Pure' is a marketing term; OFC is what there is.

@elliottbnewcombjr You'll want something to convert from balanced to single-ended at the other end of that 30 and especially 50 foot cable.


If you simply install an RCA connector at the output end, the entire connection will be single-ended. You can't have both, its either one or the other. The result won't sound as good- you may experience a high frequency roll-off (common with long single-ended connections). 50 feet will really demonstrate this.


But you can make it work:
Jensen Transformers makes things for just this sort of situation. You'll want one of their ISO-MAX products for this, perhaps a stereo unit that has dual XLR inputs and dual RCA outputs. Then you would just run short RCA connections into your stereo setup.

You'll want to order it with XLR inputs and RCA outputs.
