Recommendations for top-notch banana speaker cable connectors

Todd and reubent,
I got the AQ Suregrip100 BFA connectors and swapped them for my GLS connectors.  It was a very tight fit with my 12 ga Mogami 3103 wire, but I got these simple twin-screw-secured connectors put together rather easily.  AQ is a genius including a few extra screws as I dropped one in my carpet never to be found again.  

I got what I wanted out of these connectors:  a super tight connector to the female jacks in my amp and my speakers, better than any banana jacks I have ever used in 45 years. I will admit to that i hear no difference in the sound of my system, but that wasn't may goal.   I shouldn't bad-mouth the GLS connectors as they are very well made and reasonably priced, offering a decent fit, but these AQ's, and no doubt the Dyson's, are in a different league.  I am gonna get the Dysons for my bedroom system and one of my pals to solder them up.  

In this price range of connectors, I pity the fool that hasn't adopted the BFA connectors over conventional banana connectors. Cheers, Mark

Chiquitas. The real small ones.

Hmm, my audio quest plugs were crimp on.. I'll have to double check which model I bought. I crimped instead of soldering. I lean towards crimping because of the cold weld, which I think is more durable than solder. But really, I doubt it matters, as long as the wire/BFA connection is solid. 

Thumbs down on the inexpensive Dyson BFA's for my Von Damme cable, which is perhaps 10 ga. stranded wire.  At $12, they are cheap enough.  

Dear Tod,
It matters a lot!

AC is very sensitive to soldering. 
If you solder with "multicore" (very strong and hard to cut & melt) the sound differs from the very soft WBT solder.

Durability is just one thing, as contact area is another, but adding a soldering compound to the signal chain, is a thing of big interest.
Unfortunately, in most of cases, you must to choose priorities.

A pure silver plug that is soldered, sounds better than a crimped of lower quality metal.
But then, even this, is dependable upon the rest of materials and the whole philosophy by which the conductors and the insulation is made of.

e.g.1 : Even the highest quality soldering may easily rejected by a cable design of cotton, silk, beeswax, paper, wood, leather, oil, .....
and degrade the cable's signature as seriously as the poorest quality plug, or a shrinking tube at the end (if makes direct contact with the plug or the conductor).

e.g.2 : In a cable design which philosophy has another direction, with active shielding, or passive components inside blocks, PTFE, PVC, foam, epoxy, heavy duty triple wafer spades wrapped on acrylic, .....
 the solder is an essential part, no doubt, no concern, or second thoughts.

You know the importance of the plug at the end and how can change the perceived outcome if it is silver or copper or rhodium or gold plated.
The solder reinforces but hurts the signal flow with impurities.
