Ultimate stereo nightmare


I have a complex stereo system, having accumulated many various components through the years. I also have an impenetrable jumble of wires.  Until now I’ve been able to deal with problems that arose. Now that I am elderly I can’t easily get down on the floor to assess things. I bought and installed new very expensive speaker cables (Audioquest Robin Hood), and subsequently found that my right channel was not working. After switching cables, the right channel was still not working. So the problem is somewhere in the system.  I don’t know if it’s a loose cable or something else and have no way of tackling the jungle of wires to check it out. 
I hired a company that claims they deal with these things, but there’s such complexity I don’t know whether they can deal with it.

I hate to say it, but I am feelings the aches & pains of aging myself.

You didn't list your equipment (separates or integrated, SS or tube, etc.) and this may be helpful to know.

But, I also hate to say this, I think you are going to have to unhook that "jumble" of cables, unjumble them, and start from scratch hooking them up and see if that right channel comes back.

I know that is not what you want to hear and hopefully some one will come up with something better for you.

Same boat here. Harder everyday.

But it is worth it to "refigure" everything out. 

And make better notes to self.

If or when you figure it out, write it down, at least on the phone.

Totally recommend putting all the complex crap up for sale and going with simplifi, an active speaker setup with everything needed built in:

I agree with @kota1 . At some point, it’s better to simplify (and SimpliFi is a good resource). Do you really use all those components, or is it just "nice" to have them? When (if not now) does "can’t deal with all this" outweigh "nice"?

Well, whatever you decide, I wish you the best of luck!
