I've conducted blind testing on people and some , when they fail to hear a difference, don't change their mind at all. For instance they attribute their failure on the music used [which is why I make them pick it before the test, not me].

So what. I fail to see the relevance.

[bold text emphasis mine, to show what part I am discussing]

I suspect you are mistaken with your words "of course" and instead there's a possibility you would attribute your failure to hear a difference to something else, like, for example, the one I mentioned in my last post [the music selected for the test suddenly being deemed "inadequate to show the distinction", post test].

I'm not mistaken, and I've articulated my points and overall point of view clearly. Other AVS member can decide for themselves what is logical and/or credible for the subject of this thread.

They always have an excuse.

Well, a pair at $10 at each end of the cable would be $20 per cable times n cables can add up quickly.
ps. what is the vampire number as I didn't see a $10 banana plug.

Maybe they are called vampire because they suck you dry of funds.

I use a lot of these, handy for testing:

Pomona red banana plug #1825-2 at alliedelec.com

They come in at least ten colors.

And of course lots of these:

Pomona black dual banana plug #1330-0 at alliedelec.com

They fit nicely in my test gear and amps with standard jack spacing. They've got strain reliefs on one side and ID tabs, but I still paint one side red to keep track.

Anything ferrous in the signal path (plugs, jacks, relay parts, gold-plated steel) will introduce a tiny amount of measurable but certainly inaudible distortion. No need to worry, the distortion pales in comparison to that from solid-core inductors in the passive crossover or the drivers themselves...

Probably the most important criteria for speaker connections is that they are tight and don't fall out. The inductive kick from a disconnection under load isn't healthy for amps (especially those without flyback diodes) or crossover caps. I use "locking" banana plugs, ring and fork terminals.

Speakon connectors are the greatest thing since canned bread, but they can be a pain to retrofit to some amps.

Sources/processing: stack of stuff that if it isn't vintage now, it will be soon!
Amps: stacks and stacks of old iron
Main speakers: big DIYSG
Surrounds: Bose graveyard
Subs: a bunch

Yup, Pomona is exactly one the the brands I was talking about in my last post here. They have been making banana plugs forever. A top choice in the rest of the electronics industry.

I started with Monoprice banana plugs. After a short time, I noticed they got loose from either the screwing together or the tip started to unscrew.

My choice was to try locking banana plugs, and I got them from Blue Jeans Cable. Theirs have twin set screws, but also a wide area between those where I can solder the connection. I had to get a more-powerful soldering station (60 watt) to be able to heat them up enough to flow solder, but it works. When you buy finished cables from BJC, they weld the wire in that same space.

I make NO claim that they sound better than the cheap Monoprice connectors, only that the connection is more secure. By contrast, the bare wire connection I have to use on my Atmos-enabled speakers (to reduce how far they stick out the back) do get loose and I have to snug them up occasionally. The speakers are KEF R50, and the binding posts are very good quality. They still get loose.

SO I am wondering, am I bottlenecking the crap out of my speaker cables by using a, I assume, bad set of banana plugs.



Thank you for reading.

Russell's site is breath of fresh air in an industry riddled with lies, distortions, and snake oil.

Assuming it is gripping onto the wire correctly that's true that there's no sound difference but I would agree with KenM10759, above: they do differ in build quality and wire connection methodology. This would hardly matter in most typical consumer use where you connect them and then they remain untouched and not jostled for perhaps even years at a time, but for a hobbyist who moves things around a lot and experiments with different setups it can be annoying when they lossen and need to be re-tightened all the time.
