Do Banana Plug Adaptors Degrade SQ?

I have used the cheap banana to spade adapters from Amazon and I thought they were fine until I got a set of XOX Spade Adapters from Black Cat Cable.  
The XOX adapters not only worked better and had a better construction, they sounded essentially perfect as if there was no adapter attached.  I use them to this day and will until the day I depart this life.
Just my 2 Cents worth.

The JBL L65 looks like it has recessed binding posts on a 45° angle.

I have a pair of 4412As with likely the same arrangement.  It may be different in the case of the L65, but I doubt it.


JBL thoughtfully made the binding post spacing that matches a Pomona Electronics 1330 or 4892 dual banana plug.  That's what I've used for years.  Makes connecting your speaker cables a snap, even in the dark.

And specifically the 1330:

The 4892 is the same as the 1330 except it has a wire strain relief molded in the grip.  If you want gold plated contacts, use the 4898:

The 1330/4892 series banana plugs are readily available from the usual suspects, Allied Electronics, Mouser, Digikey, Arrow, etc., etc.

I have the audioquest wel speaker wire and I have bananas.  I doubt they would have bananas on their top of the line if they sounded audibly worse.

Bananas into 5way posts have always seemed a 'gold standard' for 'better' equipment, speakers.....

A better move would be optical, to duck the whole issue of cables and IC's, and how they can 'improve' or ruin response..

...although I can also already hear the claims of 'our optics are better than X, Q, or whoever's fibre IC....

So maybe we're better off just 'standing still'...*L*

I doubt either either Will Occur.....but, on the other hand, Could....

Of course, this is 'digital realm' stuff....
