In Reply to: RE: Installed SWO-XXX after 2 weeks. Too much 'S' or 'SH' sound. Any idea? posted by michaelv20850 on May 27, 2007 at 08:30:16
RFI's effects sound like what you describe. As the SWO-XXX appears to be more revealing, it may be revealing that defect in the rest of your system. Read up on RFI controls here. They are cumulative when done properly, so you can try something and if it works add more. I particularly like parallel RFI filerts on my AC, R-C arrays, transformer tweak, etc.
My SWO-XXX does not do what you describe and neither does my Furu Cu.

I have just put the choke 193L back and i will give it a few days to see if it can suppress RF in my system. With Furutech Cu , i don't have problem. I guess you're right with SWO-XXX is more revealing so that the bad exposed more..:) And i need to give more time for burn in.
thanks.
OK, first I should tell you that I bought mine already well broken in from another inmate. Second, my system is largely solid state, with the excpetion of a tube buffer (MF X10d) between CDP and amp.
I suspect that you can get RFI intermodulation pollution from a variety of ordinary household soruces in most situations. Consult Al Sekela's many posts on this one
I do not experience any falloff of LF and HF is qutie detailed without being harsh (once I did a minor re-burn-in) or grainy.
Downstream I have a wide variety of AC elements: Marinco, Wattgate, P&S, Furu Cu. So if ever there were a test of a mixed bag, mine is it. The SWO-XXX works great for me. Better than the Furu, though I liked the Furu.
YMMV, of course. Give it time to fully break in and then consider downstream elements and RFI controls.
FYI, those stainless steel plates might not be all the best. I'm not surprised that you got better results with the plastic or nylon plates. But a true aluminum plate probably would work very well with this setup.
You know Im going out on a limb here, especially with all the SWO-XXX lovers here, but in my epxerience the outlet is by its nature very euphonic and not neutral at all, probably due to some sort of hysteris or similar process arising form its platings.
It 'works' by pushing the lower treble/upper midrange and making it more pronounced albeit with a grainy texture, in addition to recessing the bass in parts of the range.
Im not saying its a dog, in fact the opposite as I have two in my system, well burned in with P-079 and love what it does to clarity, but I accept its not perfect and accept its grainy upper register as the small price for its good aspects. But this grainy-ness is why Im checking out an R1 (on its way thanks Alan).
HM....I would suggest that the XXX by itself is NOT euphonic....I've heard it in many systems, and with many, many power cables (primarily using Oyaide connectors). Of all the Oyaide platings, it *is* the most neutral presentation (that opinion has also been reiterated by many others). My view is that what you are hearing is due to the materials interaction (of the XXX) and other "ingredients" in your system, skewing that neutrality. It is what it is, and you are hearing what you are hearing....no argument.
Was your XXX cryo-treated? I've never experienced any graininess with a properly cryo-treated outlet. In that regard, I think you'll have a most favorable impression of the R-1.
Yep maybe it is simply 'reacting' with something else in the chain. And both the SWO-XXX units were cryo treated.
And as the original poster found, I had no tonal problems with the Furutech Gold sockets.
But their (SWO) pronounced character definitely melowed to be more than acceptable with MANY hours on them. Closer to 700 hours than 400 hours.
So to the original poster whose experience mirrored mine to start with - just give them a stiff 700 hour break in, and like me, you may find it hard to go back to the Furutechs.
Also as others have suggested try RF control particularly the Hammond 193L choke tweak.
(Im itching to try my new R1 tho....)
I guess SWO-XXX may work best with tubes or laidback system. I tried different favourite CDs which i don't see problem with Furutech Cu, and the sibilance, or the edgy sound , irritates me a lot...lol....As Alan suggested, i will give it more time to burn-in. AFter that, if it's still there, i will go back to the Furutech Cu.
I know that most inmates here pair p-079 plug with SWO-XXX, but i can 't afford another attempt ...:) and i guess it won't make much different .
By the way, i put the plastic wall plate back last night. The sibilance is reduced (strange) , but it's still there. I assume SWO-XXX is system dependent too.
Knowing that you had an all solid-state system, I would have initially suggested you try the SWO-GX, rather than the XXX. The tonal balance of the XXX is sometimes too lean for some ears, and works to emphasis the incisive qualities of (most) solid-state presentations. Additionally, installing a duplex that was pre-conditioned would largely avoid the ups and downs of break-in that you are experiencing.
You also pointed out (in another post) that the revealing nature of the XXX is illuminating the "flaws" of a bad/poor recording. Since the XXX offers a presentation with greater "micro-detail", as I like to call it, you are certainly hearing more information off the recording, both the good and the less-desirable.
Alan,
It's coincident that Chris from VH audio suggested me SWO-GX too ( I bought swo-xxx from him and it is cryo treated), but i decided to get SWO-XXX instead because of many good reviews here. What is the character of SWO-GX(bright, laid back, ...etc)? The Oyaide website does not say much.
I have found exactly what you have described in two different SWO-XXX in two completely different locations.
The outlet needs LOTS of burn-in. 400 minimum -700 hours for me. I swapped mine out a couple of times because I couldnt stand its sound, and kept coming back and trying it - third time lucky. I then went for a second outlet with an awareness of this extended burn-in requirement, and it was the same and eventually mellowed.
It also needs to be combined with the right plugs. I find it works with a P-079 which balances it out. So with lots of burn-in and the right plugs I find it works reasonably well. Without these I find the lower treble is too hot with midrange a little recessed, giving a cold metallic sound.
I think it is this lower treble push which gives it its characteristic of 'detail' - i guess its just a matter of making sure other components (and RFI) are not emphasizing or interfering in the same spot of the frequency range.
