Hey, what can I tell ya? I never claimed I had data. Data is not necessary if you can follow a line of reasoning, which apparently you can't. Demands for data. Funny!

Geoff , maybe you can help me out with this, what happened to the OP question about the silver bearing conductive adhesives ? I looked everywhere even under the house and can't figure out where the Damn subject went to ! It must have been buried in the bickering pile. What about the Adhesives guys ? :^)
HI all,
I have very recently mentioned the ECA (electrical conducting adhesives) connection approach. I have been doing quite a bit of reading on this subject, including white papers by distinguished experts in the field of electron transmission and ECAs. The conclusions all basically say or strongly imply that, crimp or solder, connections will become techniques of the past for many applications. Some ECAs contain more than 45% pure silver, in pure silicone or epoxy, providing outstanding electron transmission.
However, I just had a thought on connecting IC wires without any RCAs or ECAs.
The signal wire would be inserted into a PTFE rod, much like an RCA center pin, drilled centrally for the wire size. The inserted wire would be, bent over the tip of the rod and, run down the rod O.D. This assembly would be a sung fit in the central opening of the female connector.
The return wire would be secured to the female connector O.D with an O ring. I am presently looking at PTFE, FEP and AFLAS O rings. The wires would be easily removable, have the desired single point contact, and reapplication would be very easy. This would be great for my home setups because it’s been at least 10 years since I added a component (Audible Illusion M3A). It is rare that I swap out components or move them to different locations. All thoughts will be greatly appreciated.
Thanks,
henrylr
made IC's like what you describe. Bare wire inserted into a insulated tube that were wound around a center pin for the male connection and then the negative was fitted into a hollow sleeve which went over the negative RCA terminal.A q-tip handle works well for the positive, BTW. Cut a slight groove down the side and across the end for the wire entry.
No solder at all, just essentially compression fittings. Worked ok, but after a couple of removals the wire would break at the bends.
May not be an issue for you,
YMMV

May be for outside of RCA ?
Or one for each of them, if RCA connectors are far from each other.
Or may be not necessary for negative contact ?
Just an idea !

Interesting idea, however, I've been wondering why we need cables.
We see photos from Mars and there are no incredibly long cables. Astronauts talk to us and there are no incredibly long cables.
I believe that wire producing industries have high stakes in keeping us tied to cables and wire, but the audio industry and their dealers seem to take the most advantage of cable/wire so called magical properties and make tons of money by selling us snake oil and other preposterous solutions to make our systems "perfect".
While I am not an electrical engineer, I have been an aerospace mechanical engineer for over 40 years and I have to ask/wonder why there has been no technological tickle down effect that would reduce our dependence on wire/cables, some of which are only a couple of feet long. This need for cables seems like a money generator for certain industries and audio dealers. Can anyone shed some light on why we suffer this burden? It may be apparent that I have no trust in the audio world of producers and dealers.
Thanks,

The new Oppo 105 like its predecessor Oppo 95 eliminates the need for high quality external DAC (and digital cable) by incorporating a very high quality internal DAC - two 32 bit DACs. Amplified Loudspeakers obviously eliminate the requirement for external speaker cables. If you are clever you might be able to eliminate the need for power strip(s) and some power cords. So there are ways to reduce number of cables/cords.
As you probably all know, the OPPO machines and the Samsung Smart TVs, as well as other devices, have wireless wi-fi capablities. Are there transmitters and recievers that can eliminate the need for ICs, from various source components to a preamp and, from a preamp to an amplifier?
Thanks,
henrylr
Most of the current models of TV sets have wifi capability and so do much of the current AV receivers. Considering that most Blu Ray machines have the capability too, including the $75 Sony machines, I'd say it is possible to have only speaker cables hooked up, and, even there, there are wireless speakers ( built in amps) available. quality sometimes is questionable, though.
Stu
the trend is to wireless. you see this in Apple stuff: Airplay and other similar devices.
Download your music from the "cloud" and send it to your wireless router and then its a short IC to your preamp. In fact many receivers have the capability built in and so do many Blu ray machines and such.
Wireless or at least minimal wiring is already here.
If you're analog based, (ancient TT's like me) then of course all this throws immense amounts of RF into the atmosphere. Not really great for guys like me, but of course,
YMMV
Stu
Thanks for the reply. I have an oppo 95 which has wi fi. I am more interested in how I can eliminate the ICs between my various source and amp components, ie: Meridian CD, turntable, preamps and amps.
Thanks,
henrylr
The more I think about it my inquires about tweaks, to existing technologies (ie:wires) was interesting but, were not going to lead to really innovative techniques. Are there any new technologies for sending audio signals between components without using wire?
Thanks,
henrylr
the problem is that any need a format converter, on both ends. Extra components, extra noise, extra distortion.
Not good.
Bass is supposed to sound big. 6.5" is not a woofer size.
your queries certainly have revived some ideas I had long forgotten about. The Yamamoto cable was not well received: perhaps not enough panache without the use of 6N wire and such. Still considering that wconnections have been around for over century, its amazing that more alternatives have not been put forth.
I hear rumors of optical hookups, and I believe Harmonic Tachnology came out with a set of cables which uses optical light transmission for the signal. That still requires a cable interface, though.
To go wireless, as you inquire about, would demand all digital components, because that format transmits data more efficiently wirelessly (well, with way less bandwidth requirements anyway). Technically, there is no reason why, if you are digitally based, that should not be feasible. Just look at how small and cheap wireless routers are these days. You could eliminate the analog stage in a digital player send the signal to a preamp, process it digitally ( they do that already with surround sound), and then spit out the signal to the receiving router in an amplifier which these days can be digital also.
Its only a dinosaur like me with lots of LPS and a turntable that need the wiring. But then again, I just heard rumors of a light triggered cartridge (toshiba had one way back in the quad LP era).
YMMV naturally,
stu
My last note may have seemed like a diatribe against audio manufacturdealers ect.. That was not my intent. Some equipment manufacturers, like Eichmann and a few others, and some dealers are probably on our side.
