Need recommendation for hi-rez xlr plugs for re-termination project

@mitch2 My reference to OCC Pins was in relation to the Furutech Connector linked a prior post.

In that same post, I believe the ETI Connector is a Beryllium Copper 

@lcherepkai maybe your equipment does NOT follow the AES standard?
If it does or does not, then that could be a factor.

@pindac - ETI also make the silver ones, which is more $ than the copper version.

Also, do you find unbalanced/rca interconnects to sound generally different or do they sound relatively homogeneous as well?

Largely they sound the same on my system. However preamp output impedance and amp input impedance can play a role.
So knowing your preamp’s output impedance and amps input impedance may be worth understanding. 

The cable/wire that is in between the XLRs (or RCAs) also can play a role… particularly the capacitance, but mostly when the output impedance starts getting high.

@holmz Your enquiry is a good one for me to respond to, as I am in a position to offer a evaluation from a few experiences encountered and a experience yet to be encountered, but have the first impressions from somebody who adopted the methodology following my encouragement to look at the idea.

Due to a need to restructure the home, the HiFi System has been slowly be packed away for the time when the home is no longer habitable. This has been a deterrent to my being proactive and continuing with completing an additional design for the Bespoke Built Power Amp's.

The Amp's are to be returned to the designer/builder and produced to have a Balanced and Single Ended Circuit. To work in conjunction with the Power Amp's I am having a Bespoke Built Pre-Amp to have both Balanced and Single Ended Input/Output.

I have been very specific about the signal path wiring to be used in both the Pre' and Power Amp's  

I am going to have a Balanced System, but am yet to use Balanced Signal Path in my system.

I have been demonstrated a Wire I am seen regularly exposing myself as being a advocate for it. with a Single Ended connection with Pure Copper Low Mass / Low Eddy Connectors on the Cable and Chassis Input. I have also been demonstrated the same Cable in the same Length with Pure Copper Connectors that are not a Low Mass / Low Eddy connector. The Benefit of using Low Mass / Low Eddy on umbilical connections is from my experience one to be aspired to. 

I have already received reports from others who have adopted this method and the feedback about the betterment is seemingly similar, if described in different ways.

The individual who introduced me to this alternative type of RCA Connection informed me that the XLR Connector is inherently a Low Mass / Low Eddy as a design. I have not received any countering of this to sense the description is with fault.

As for Silver being used, I find the impact it has as a Wire hit and miss, a certain wire type used at a particular interface can make a good impression on myself, but Copper will usually take the place.

I have one of my prefered Cables in 0,7mtr with Aeco 4055 Pure Silver RCA's and the same Cable in 1.2mtr with Aeco Copper 4045 RCA's.

The Copper is attractive at all interfaces used, the Silver at a certain interface can make a Vocal sound slightly Nasal sound.

To get to the the bottom of it, I had the two cables used in another system to see what could be detected. I did not inform anybody of my reasoning just that different length and different RCA Types were to be used.

One comment from one attendee about the Silver RCA Cable was that a Horn sounded like VuVuzela that found fame as an annoying instrument in the crowds at a Soccer World Cup. A Harsh statement used with humour, but a detection the Silver was having a impact that was being a deterrent and not desired.

A Friend has recently Built a Balanced Pre-Amp to work with a Balanced Head Amp, this Pre and Head Amp design are both familiar as a Single Ended Build. The Balanced Design is using Neutrik's on Chassis and Cables.

The overall assessment of the equipment with a limited run in time following the debut demonstration, is that there is something more correct about the Balanced Presentation, less constrained and with additional detail, would be a reasonable description of what was discovered from a very short usage period.

On this Forums Helix Cable Thread the last posts are by an individual who has now produced XLR Connection Cables to this design using PC Triple C Wire, this is a Wire I highly recommend, the individuals first impression even though not overly descriptive leads one to believe a improvement has been discovered over their previous builds. 

I have put OCC Copper Wire Cables back into the home system to finalise the assessment of PC Triple C, and OCC Wire is Superseded.

You can read my posts about this wire in other threads.     

Abbatron / GH Plugs. They make them in Gold plated or Silver plated contacts:

"The GH XLR Connectors feature beryllium copper sockets in the female and tellurium copper pins in the male connectors.  What does that mean??  Approximately 3X the conductivity for a cleaner and fuller sound.  Orientation of the colder contact allows quick soldering and the "chuck" style strain relief accommodates a variety of plugs."

Approximately 3X the conductivity for a cleaner and fuller sound.

I find ^that^ a bit far fetched…

3x the conductivity of what?  (Pure copper, aluminium, ??)
