In Reply to: RE: R-1 in. Its quite something posted by ArdRi on August 10, 2007 at 10:02:46
Hello Al, Everyone the R1 was installed onto my puresinewave Inverter for 2 week evaluation .. I was not happy camper installed a cheap hubble that was cryo'd all the music came back...no more tubey sound or undefined sound ..there seem to give you more false information and or resolution and more bass bigger bass but it just didnt come together.
my audio room is almost done I will give another listen on my dedicated circuits..instead of my Inverter..
I hope this helps someone they are expensive

Follow Ups:
The Oyaide outlets are mechanically strong. If mounted on a metal chassis that is also acoustically lively, I would expect some interaction of the acoustic resonances of the outlet and chassis.
With the system off, try tapping lightly on the inverter casework or chassis metal near the outlets with a finger nail and listen carefully to the sound. If there is any tone in the response, try damping the metal. A plastic bag of sand or fresh raisins works well for the experiment.
Vibration isolation may be more important for this inverter than for any of your other audio components.
Your the first person I heard of with a negative experience with the Oyaide R-1. To be honest I find your conclusion a bit strange as you perfer Brass alloy over the 98% pure copper Oyaide R-1 outlet. Based on my experiece, going back over three years, every time I replaced a brass alloy connector (rca, speaker spades, A/C plug, outlet exct) with a pure copper connector the experience has been positive. The collective improvement of replacing all of the brass connectors in my system with pure copper as I have now has been sonically dramatic in the positive direction.
I guess everybody had there own opinion but for me high purity copper is the way to go for audio and video connections and I avoid brass as much as possible.

Beryllium copper can be quite a bit less conductive than pure copper, although it is higher than most brass/bronzes. From what I've gathered, the electrical conductivity of beryllium copper ranges from 16 to 65% IACS, depending on alloy and temper. Best case, this is 35% less conductivity than pure copper. I'm not saying this is necessarily a huge issue, but the difference is surely worth noting when comparing to a pure copper product...
When looking into having some custom tube sockets made years ago, I learned BeCu was commonly used for tube sockets in mil spec apps, but was being phased-out due to the hazards of working with Beryllium. Perhaps the processes now used are safer for the workers, since I made my inquires. Below is a link to IACS of some of these materials:
Hi Chris,
You are corect Beryllium is not quite as conductive as 100% pure copper conectors but it's not very far off sonically. Some differences sonically with beryllium I noticed when I switched my amp binding posts in my Cat JL2 to pure copper is the low bass was slighter fuller (fater) and the midrange had a little more body, fat and substance. The detail level between the two coppers was similar and I found berryllium copper very similar overall to pure copper but there still was a difference and I perfered pure copper if possible but to be honest in most cases it was very close.
To the best of my knowledge no manfacture makes a pure copper wall out so the the Oyaide R-1 is probally the best quality outlet for most audio and video applications. I perfer to use the top of the line copper base Vampire male and female rca's and the excellent FIM 302 and 302 pure copper A/C connectors on my powerchords. I have removed all of the stock female rca's on my audio equipment and replaced them with vampires with excellent results.
Interesting the CuBe were used on tube sockets. I hope my equipement have such sockets but I suspect not as they are more modern.

Here's another link to various copper/brass/bronze alloys
Hey Larry!
Disclaimer--Yes, I am an Oyaide dealer. Yes, I sell cryo'd R1's. Yes, I like Oyaide...why would I sell it otherwise?
Everyone who knows me knows that I don't post here very often, but I thought I'd chime in a bit on the R1's.
I have found that the Ultimo's and the R1's take a VERY long time to break in. I have many customers who are reporting that they are still hearing changes up until the 500 hour mark.
After your room is done and you re-install it, let something draw current through it for another 300 hours (at least) and report back. What you are hearing sounds a lot like lack of break in.
And, as an aside, the R1 may not be the "best" solution for everyone. The XXX, GX or DX may fit into someone's system better. Heck, maybe even a different brand is called for. There's no right or wrong answers...I wish there were!
It's all about synergy, baby!
Peace, Love and Happiness to Everyone.
Lee
