Just a heads-up. This is the best price found for what I consider a classic tweak. Simply replacing the often cheap, stock binding posts of a loudspeaker or power amplifier, with an unplated, high-mass pure copper binding post.

The Cardas CCBP Pure Copper Binding Post sounds good with any type of speaker connector, as well as bare stranded conductors which I use to connect a pair of DIY nearfield monitors, positioned at console-height above ear-level focus, just over the top of the head when sitting right in front of the dispersion patterns.

So what the Cardas CCBP Pure Copper Binding Post provides to my ear is a very smooth and warm presentation without affecting the spatial and dynamic aspects of the signal, with a natural-sounding leading edge. It's a more streamlined and detailed but subtle sounding presentation, to my ear. I've enjoyed the classic unplated Edison Price Music Posts for many years, and also enjoy the bare Cardas CCBP Pure Copper Binding Posts in the same manner.

I will have to try these. I too used to use the EP posts on my projects and was/am happy with the results. Thanks for the tip!

Unplated copper has the issue of oxidation possibly interfering with the signal which slowly sneaks up on you after a long period. Also true of the Edison Price.

The Pomona Tellurium Copper purports to avoid that problem. I've used them on speakers for years and never seen oxidation. There's also a similar product from the Taiwan outfit Vintage Audio Lab.

Handmade, BTW, is a great under-the-radar source for parts that's been around forever.

Sonic Craft also sells the Cardas CCBP S and CCBP L speaker binding posts. $23.75 and $24.70 respectively. I recently replaced the binding posts on my speakers with the CCBP L and like the results.

Have these on my speakers. Filed the gold plating off my speaker cable spades to reveal the bare copper underneath. I tighten with a small wrench. Some maintenance from time to time due to oxidization. Otherwise have never looked back. When I look at debates between gold, rhodium, etc plating, I just shake my head when the purest conductor is right there in front of you. And the plated versions cost more.

Using bare copper with some expected maintenance should fall on a list of "you know you're an audiophile when..."

Cheers!

The best - two thumbs up! I like these and that's a great deal. They do tend to get tarnished after awhile and are a little hard to clean. I also really like the Vampire BPHEX/CB which are a hell of a lot more expensive.

Both are a bitch to solder wires to event with a good iron.

Those look so much like Edison-Price speaker binding posts that my first thought was Cardas took over their manufacture or marketing or both. The only issue with the EP posts for me is that if you tighten them down max, the thread tends to slip, due to the notch in the male piece.

Speaking from years of experience, unless one lives in a corrosive environment, I have not found detrimental sonic effects due to copper oxidation, especially if an end user pays attention to the state of their connector interfaces. Even plated I/O can involve conductivity issues. My primary interest as the OP in this thread is to give a thumbs-up to how well the product sounds from an audiophile POV. It's a viable and smart option for those who seek a flavor other than a plated connector, of which I have nothing against. In fact, I'm an advocate of plated connectors, more often than not.

Cheers, Duster

It's true that the old school Edison Price Music Post is somewhat vulnerable if treated in a heavy-handed way (too much torque), but the Cardas copper binding post is more durable from an end user POV. I've had no problem with either connector over the years. YMMV

A good soldering iron AND an extra pinch of rosin/flux recommended.

Cheers!

I use my trusty Hakko 936 at approx. 750F. A wide chisel tip spreads the heat, and the solder (Cardas eutectic) nicely.

The superior conductivity of pure copper, including thermal heat conductivity and the energy storage capacity of copper is quite different than a brass connector, where the heat is better localized during the heat transfer process in order to quickly form a robust solder joint. I wonder if a high-mass copper binding-post were mounted on an aluminum heat sink, if the quick thermal conductivity of aluminum with its thermal dissipating storage characteristic might help transfer excess heat in a similar manner as an unused rca jack on the back of a VCR or such as recommended for cable terminations with Bullet Plugs, WBT NextGen, and KLE low-mass rca connectors. Either situation has to do with thermal dissipation.

That makes sense and has given me an idea for some upcoming work I have to do. One of the nice things about the Cardas is that you can unscrew the tops all the way off. I wonder if replacing the caps with a row of aluminum nuts would also help dissipate the heat while soldering. Can't hurt to try.

I learned my lesson years ago. Without them, soldering takes much less time.

I'd be interested in your experience with the aluminum nuts....'ya nevah know.

It might well. That would, I'd have thought, make it inadvisable to try. Would it not be better to mount the post in some form of insulation (such as a scrap of medium-to-heavy PVC cable sleeving) so the heat is kept local and the joint made quickly?

Can't hurt to try.

Hopefully not but I've damaged things (many years ago, you understand) by taking too long to make the joint.

I can't remember for sure, but I think I have the long rather than the short version Cardas. So the soldering point is further away from the teflon. This would affect the scenario somewhat versus the short version shown in Duster's original post.

Thinking ahead further, the longer would also let me add extra aluminum nuts to both sides of the barrel for soldering. Then remove the nuts before soldering the other end of the wire.

Thank you Duster for the OP and for explanations that help us put logic into practice.

Cheers!

Jonesy

Edit: I still have and use WBT silver solder with lead. Lower melting point.

The site you linked to has them plated for around the same price. I would imagine that the Cardas being copper, that you should be carful about tightening them too much.

Definitely careful when tightening. I've seized the posts on each speaker one time. Was weird. Like I had skipped a thread or something, as they froze up when undoing them. Both speakers, same day. Too much spinach? More careful now. I still use a wrench to tighten, but a very small open end one. Have the seized ones still kicking around. Not sure if there is anything I can try. They feel like they would definitely break off if I tried to undo them.

Cheers!

Your prized Anniversary Edition was assembled with a Hakko, a rather burly piece of gear. So I trust you are enjoying the results? :--}

Yes I am. Been cooking almost continuously since it arrived. In fact, I'm cooking speaker cables for my electrical engineer neighbor right now who has just bought a new DAC, transport, and speakers and is unhappily learning that wire isn't just wire and outlets aren't just outlets. 6 months ago he would have laughed me out of the room at the notion of break-in.....now he came to me asking if I'd cook his new cables for him. See what you started? :-)

My Hakko is head and shoulders better than all but the real $$$ weller stations.

I still have but no longer use, an Unger Imperial.

Just to be clear, I was only picking on Alan. I'd love to have a Hakko, but the budget leaves me slummin' with my Weller. No complaints at all with it, but it's certainly not a Hakko.

Years ago when Aragon was a standalone private company, I called their tech line to discuss tweaks for my 4004 amp.. I spoke to one of the owners, real nice guy. During the conversation I just had to ask. These Edison or Cards BPS are such an improvement why didn't they use them ? He immediately agreed but quickly reminded me that the would never get UL or type approval anywhere with exposed non insulated knows!

I had used cardas before, it is a good binding post, good price for sure. However, WBT nexgen or Furutech occ low mass type is definite better, very expensive though.

Certainly no offense taken. Believe me, when I got the Hakko it was a night / day difference from my 40 year old (or so) Unger and certainly a real step up from the stuff we had at work. Digital control alone is 'worth the price of admission'.

I wish my EYES were better!

Is the hole at the end of the cable connection meant for bananas? Or is it just a hole?

I'm a big fan of unplated copper binding posts. I made a point of using a set for a DIY full-range assisted single driver nearfield monitor project with AMT tweeter. I had enough audio dollars to spare to include my favorite type of binding post. The presentation is both meaty and subtle in nature. BTW, I was initially concerned about the corrosive nature of bare copper, but have found no issues over the years regarding that particular issue.

I've had the Cardas CCBP Unplated Copper Binding Posts installed in my Rogue Sphinx for about three weeks now. Very easy install. The new posts have brought more warmth and musicality to my system; exactly what I was hoping for. Thanks again Duster.

what is an issue for me is the lack of a lateral hole through the post.
I like to insert the bare wire in there and tighten the nut.
I could attach a spade with set screws, but that seems to negate the purity of the bare copper post.

jhrlrd, I also prefer having the option of a lateral hole. But, I had no trouble attaching my Duelund DCA16GA wire around the post and getting a tight connection. I suppose wire gauge, pliability, etc comes into play here.
