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

Those Cardas adapters are excellent quality if you don’t mind a SE connection to an SE device. With the Jensen you retrieve some of the benefits of balanced. I haven’t thought about this in years, so I leave it to Atma-sphere.

Conductivity of copper is a constant. What you want is resistance per unit of length. There are tables on line for that in terms of AWG. If it even matters. Yes, 16ga has a lower resistance per unit of length than 22ga.

I would have sourced the transformer from Jensen and installed it right at the amplifier input, saving several interconnection s in the signal path.

What's a "Sony Carousel"?  Is the idea from "Mad Men"?

Do what Ralph says. He has been answering this question and similar questions for decades posed by people like us. He knows what he is talking about.

From reading your OP, I get the impression you intend to use XLR to RCA adapters at the RCA inputs to your 2-channel single-ended amplifier.  That will "work", but as vinylzone said, you won't get all the benefits of balanced lines.  Use good quality adapters, for sure.  Cardas makes nice ones, albeit the best adapter is no adapter.  If your amplifiers are not internally a balanced circuit, that's the best way to go, and I wouldn't worry any further.  You could also have your ICs terminated in male RCAs, rather than XLRs, to avoid using an adapter.  How to do that optimally, with respect to ground, is another matter.
