Hardware... Receptacles, plugs and power inlets
« on: 12 Jul 2015, 08:36 pm »
I am starting a new thread here to establish a place where people can post for others about their experiences with the I/Os of electrical power in music reproduction systems.

It was a revelation to me over the last few years about just how much the connectors in our gear, cables and wall outlets effect the SQ of systems.  Started when I began auditioning outlets for the BUSSes.  I spent a couple of hundred bucks on relatively generic receptacles.  When I say relatively generic, I mean those available through commercial vendors for construction, residential through hospital grade and MRI receptacles. Even among those there were differences that frankly just didn't compute until I looked at the different alloys available, the thickness of the contacts and resulting spring tension, housing build and other physical aspects of them.  I found good to great receptacles in almost every vendors' product lines, with a couple of vendors products standing out from the general fare.  Some sounded loose and farty in the lows and vague in the highs.  Some were very tight and controlled, others were great or terrible in the mids.  Kind of a stunner to me that there could be that much difference in SQ because of a receptacle or connector, but I could not deny what was going on.  Other people came to the same conclusions through their own personal experiences.

That is what I want this thread to be about: an informative, educational group of posts that is oriented to becoming a reference for others to use for system voicing.  With this in mind, please limit posts to personal experience and observations.  If and when there is a change for the better or the worse in your system because of an electrical connector change please share it here for everyone to see.  Include system details because types of systems dictate different types of connectors be used to get that systemic synergy that makes music reproduction special and engaging.  As always on this site, there will be no name calling or derision by the inexperienced.  Just because we "think" something is true means nothing unless there is empiricism to back it up.  The "I read it in a book" argument is not acceptable here.  Basis of all of this is a desire on my part to help others to get absolutely killer sound without spending a million dollars trying everything out there, when someone else with a similar system and tastes has found something that works for them.  Perhaps it may work for you without needing to reinvent the wheel.

Let the mirth and frivolity begin!   :thumb:

Potential to be a great thread here! There is much debate using different Oyaide connectors in other circles as well, but the information and details are lacking, then  the threads get crapped all over. This caused the threads to die, of course... Hope this thread will be taken seriously and remain informative.

I really look forward to what the GTX brings to my experimentation, and will surely post here my findings.

I've Ben getting some interesting feedback via PM, but won't post that content without permission.

Please post your observations to this thread, guys.

I'd like to gather input from the crowd on experiences with the Neutrik Powercon inlets. 

Dave, I don't know if you recall installing the Neutrik on my unit.  I figured it would be a nice, sturdy, worry free way to connect power to the Buss.  I've certainly had no issues with it, but after hearing so many gush over Furutech FI-50 connectors and such, I just wonder what the differences could possibly be? 

I was once exchanging emails with another manufacturer and I told him about the Neutrik inlet, and his response was "that's not hi-fi".  Huh?

i guess my question would be "what IS hi-fi"? 

There are times when items are chosen for neutrality.  I use the Neutrik connectors upon request because they meet that regimen.  The 20A Neutrik NAC3 connectors fit that bill.

OTOH I think that the Neutrik NAC3 32A /250VAC connector is the finest transparent connector available.  If by "hi-fi" the person means colored in sound, I would have to agree with him

I prefer to choose my colorations with receptacles and cabling.  To each his own.

BTW:  if they are good enough for the Audience Adept Response conditioners as well as the other manufacturers that have adopted them, I reckon they are good enough for the BUSSes.

Just sayin'...

Occasionally I get questions about what are the best materials for electrical contacts.  Here is a chart of conductivities for common materials.  The materials that we are normally seeing in receptacles are brass, red brass, copper (Furutech GTX), phosphor bronze and beryllium copper (Oyaide), CDA688 aluminum brass )Pass & Seymour 5362A).
 

Material IACS   % Conductivity

Silver   105
Copper   100
Sterling Silver   96
Gold   70
Aluminum   61
Beryllium copper 21
Nickel   22
Zinc   27
Brass   28
RedBrass   37
Iron   17
Tin   15
Phosphor Bronze   15
Lead   7
Nickel Aluminum Bronze   7
Steel   3 to 15

On a slight tangent, I recently purchased AudioQuest 1000 Series Banana (Silver) speaker cable terminations.  They specify "Hanging-Silver directly over Pure Red Copper".  Are these adjectives anymore than marketing enhancements to the core silver or copper metal? 

Thanks

The only time I ever saw the expression "hanging silver" was used in conjunction with sterling silver, IIRC. Sterling silver is about 92-93% silver with the balance being other metals, usually copper.  Oddly enough its electrical conductivity is  ~ 96 which is not quite as good as the native copper.  It is there because the oxide of silver is just as conductive as the parent metal and does not tarnish easily.  Red copper (Alloy 110) = ETP copper + 99% copper without alloying materials other than what are present in the refined copper.  Red copper is what comprises standard copper wire.  It is a lot better than brass, but not as fine as Alloy 101 copper which is defined as oxygen free.

I love marketing departments.  If you can't impress then, baffle them....

I listened extensively to the Furutech GTX-Gold which was recently installed on my wall. It took longer to break in than I expected, but now it's sounding really good. A tad slower and laid back than the Maestro, but with better detail retrieval and it's cleaner. With well recorded CDs, differences are minimal, but with the remaining 95% of my CDs, the differences are startling. Definitely a worthwhile upgrade. I'll swap out the Gold for the Rhodium in a few days and post the results here.

I think I can predict what you will post re: the rhodiums....

There is no doubt Furutech makes a great outlet. But the gold are way too soft for me. I think I might order 2 Rhodiums today. The leading edge and sparkle are gone with the gold. Pretty boring.

I've had the rhodium in the wall since last Monday, replacing a Maestro.  The outlet was burned in already.
 
The improvement in detail was immediately obvious from note one.  Not hard edged detail, but natural detail accurate and true to the recorded event.  This is a neutral outlet.  It simply lowers the noise floor and allows you to hear leading edge attack and delineated or gradual decay more clearly, especially on bass notes.  Not only are stops and starts more obvious, but the fine harmonics and timbre of instruments between each end of the note.  To say I was surprised by this, from an outlet, would be an understatement.

As a metal and hard rock fan, the price of admission would be worth it for kick drums and double bass triggers alone.  Clear as day.  In my system, bass was the biggest improvement.  It doesn't stop there however, but it was slightly less noticeable higher in the frequency range.  I don't want to sell it short, because I'm sure someone could disagree with me, but this was my experience.  I will also say that there is a smoothness here that the Maestro doesn't have.  You'd never know that though unless you compared them.

Drawbacks?  None, really.  Except I've gotten used to it now and want another one for my Uber to plug my amp into.  My system could be described as "musical" more than "detailed", so for me this was exactly what the doctor ordered.  If you are teetering on the edge of hardness/sibilance, look at the Gold.

Speaking of the Gold, I have one burning in while it feeds my two plate amps (bass drivers on Hawthorne Trios).  I really don't feel like installing it in the wall for a comparison and would rather return it, but I will anyhow and share my impressions for the AC community.  Who knows, maybe I'll prefer it.

Give the Gold more time. That was my initial impression, as well, but it takes a while to break in. When it does, it still may be a bit too soft for your tastes, but it's certainly not boring. It's a clear improvement over the Maestro.

I installed the GTX-Rhodium in the wall which replaced the GTX-Gold. The GTX-Rhodium is magical!

As everyone else has indicated, the Rhodium provides another layer of detail, but it's doing more than that, and I can't begin to describe it. More importantly, it's hard to believe that a receptacle can make such a huge difference.

Yeah! I have 5 outlets on the back of my conditioner and with any luck 2 will be gold, 2 will be rhodium, and one will be a Maestro.  I am targeting the rhodiums when they arrive for the amps and the very front end devices. And the gold for the secondary items. We'll see how that rolls out.  Off to France next week so it may take me some time to do this project.

Yeah, I think a combination of the Gold and Rhodium will work well. You'll have plenty of options for determining which components work best with either Gold or Rhodium. Make sure you put a Rhodium on the wall, though.

So what changed from your previous comments on the gold being too soft and boring to wanting two of them installed?
