An audiophile quality way split speaker wire for a sub connection

I have been searching for a solution to this problem for over a year and am just amazed at the absence of information. I have an integrated amplifier (Rega Brio) that is connected to a pair of speakers (Kef-LS50) and a subwoofer (SVS SB1000). My amp does not have a line or sub out so I have it hooked up via the high level inputs. Particular to this sub there are no high level outputs, so the speaker connection cannot pass through it. This suits me fine because I don't care to have the connection to the Kef LS50's to 'pass through' anything on the way.
 Here's the dilemma. The one set of speaker cable outputs on the amp has to connect to the Kef's and the sub independently. Right now I am using an $80 speaker switching box to make the split for the 2 connections. My concern is that the box is introducing noise. I recently eliminated a high quality RCA switch from my system and find the sound to be much smoother. I have purchased a banana splitter, but it requires that one of the speaker wire be stripped and screwed in. It doesn't seem wise to strip the banana connector off of a high quality speaker cable. A male to 2 female banana connector would work, but they don't seem to exist.
 BTW, I am using inexpensive speaker wire right now, and am prepared to replace it as part of a solution (either way will be doing this). 
Bi-wire cables won't work, because the 2 sets are together preventing the slack to connect the sub a few feet away.
 Please, and thank you. Any ideas or solutions are welcome! I am upgrading my amp to a Rega E-licit R which has a line out for potential  connect to the line in part of the sub. This seems like it could be a compromise due to the  supposed need to keep the voicing of the amp, but maybe it would be fine. The best solution would be high quality speaker cables that have 2 sets spliced together on one end with a banana connector that is done by the manufacturer. This is the unicorn. Sorry for the long post, I am trying to preempt a lot of back and forth.

I am confused a SVS SB1000 does have volume and cross over frequency controls. These are key to feathering in the bass to prevent big bumps where the frequencies are duplicated by both main speakers and subwoofer or troughs where the main drops off before the sure takes over. None of this has anything to do with speaker cables. RCA or balanced interconnects preamp to sub. Those boxes can be really noisy... no boxes for splitting.
.
So if your preamp does not have two outputs you use a gold platted splitter.. I have used these for years on some of my systems.

Using subwoofers in the hone theater setting is completely different animal and controlled differently and generally not nearly as high fidelity... it is for special effects. You don’t want to use this kind of setup for audio only.

Yes the sub has a volume, crossover setting, and phase dial. The sound is almost pristine, except some static noise that I suspect comes from the switch box. Okay, you mention a gold connector. The issue is that I want to merge the 2 male banana plugs from the speaker wire into 1 that can plug into the amp for each side (positive and negative). A Y -connector for banana plugs. I simply have not been able to find one. If you could suggest a link to a connector, I could look at what you're talking about.

I guess I wasn't clear. The question is: how to get speaker cable to the sub when there is only one connection to the amp that is being used by the full range speakers.

Easy stuff really. The problem is you want to connect the speaker cables to the sub in a very clean way. So one way to do that is one cable run with bananas from amp to bananas on the the speakers. Then you can run from the speaker to the sub, with spades for the speakers and bananas to the sub. So the speaker with have a spade connection and a banana connection (or just use bare wire).
