Model E15

bare wire. why add another connection into the circuit if you do not have to? binding posts are made to accept bare wire. sure a pain to connect, but once done typically not visible. pure snake oil, only advantage is if equipment will be swapped out on a regular basis ( store display racks etc) why waste money on them.

Please, tell us how adding another connection at each end of the wire will help. Have you ever even bothered to measure the resistance created when you add your beloved banana plugs? The difference is typically negligible, but is measurable with even a basic quality dvom like a fluke 87. It's not flawed logic, it's fact
But hey what do I know about an ac circuit? Only been an active maintenance technician troubleshooting shorts, and so much more for over 20 years now


It's fine to state you feel my logic is flawed, but when you back it up with nothing (probably to justify the snake oil interconnect you paid %20 of total system cost on) where is your fact based scientific research and data to prove it sir? It doesn't exist, plenty of data showing how connections, particularly poor connections, can and do cause electric signal degradation. Audio output is nothing more than a bunch of ac voltage at various hz. Anytime you put a break in the line and add a connection the signal is degraded. Period.

Your assertions are incorrect. There are several disadvantages to bare wire connections at speakers and amplifiers, including oxidation (banana terminations are typically gold/rhodium plated), strand breakage, shorting, etc. I too use a Fluke 87V for quick measurements, but I more often use an HP3478A, as it’s much more accurate for electronics work - and I can assure you that there is no added resistance or signal loss with bananas. If you are measuring added resistance, then either your measurement method is flawed, or you are using extremely poor quality banana plugs.

Also, there is a significant difference between an electronics technician and a maintenance technician. Audio circuits are far more complex than electrical supply circuits, and your expertise in the later is no guarantee of proficiency in the former. If fact, your assertions would suggest that you have little experience with audio circuits. If you prefer bare wire connections, great. But saying bare wire is superior is simply incorrect. Period.

@gyosa - woh, those are of nteresting design. (at least this first example I came across is, to me, somewhat unique)

Yes, I was reading about the wager bit. I like that.

I've used spades that have upturned lugs at the end, and grip lines on them, which help to maintain the binding post nut grip. These work pretty well, but that compression wafer, acting like a spring or elastomer seems like the ticket.

I'd like to try these. Affordable, too.
Curious about that "Wonder Solder". Need to read up on this.

Are the connectors pre-flowed with solder, so that you only need to heat them once assembled, or is it a small measure of solder off of a spool that they provide?

I like the mechanical crimp in addition to solder.

I like it. Nice.
