two bananas into one - widget?

does anyone know of a widget that accepts two banana plugs and ends in a single one? reason is - my speakers like to be biwired (don't go there - have tried all permutations and they really audibly do), while my amps have single banana sockets with a cross-drilled shallow hole for bare wire. I can get both pairs in a t 90 degrees , but it doesn't feel that secure on the pair on the hole. I can't strip back to wire as they are VdH carbon fibre jobs, so a two into one 'splitter' would be handy (as long as it didn't affect the signal itself too much..)

 

Something like these might be useful:

Check around at all the various cable connectors web sites too.

 

...of course, you could do what many Audio Stores do; make up your own y-lead using the same type of speaker cable with the appropriate plugs/sockets terminated.

Or, use stackable banana plugs at the amplifier end. That would only require a re-termination of the plugs on the amp end of the speaker cable.

 

that's a good suggestion - I'd only need to get one set of cables reterminated with the stackable plugs
