Hi,
I have vh audio flavor 4 connecting to Oyaide SWO-XXX. Even though the connection is tight if not saying way too tight, the power cable is heavy and it's sagging. I have to attach a string to cable and lift it up and connect the string to wall stud. It works fine but it looks untidy. I am trying to figure out a better way to handle this. Any idea would be greatly appreciated.
v.i.
Million miles from home.
.....the audiophile community has not gone to a PowerCon type connector for power cord applications.
Here are my DIY versions.
Others use glass glasses, ceramic insulators, empty CD jewelboxes, etc.

It is a retrofit and it alters your equipment, but great stuff.

Life is a lot easier now that I don't use the Aeros with the ball bearing races that needed to rest in the center.
How's it going, Mike? Some of these replies...the things people come up with??? Lets try something simple....I'm assuming you are in the US, so this tewak if for US only, but can be easily modified for UK and Europe. Pick yourself up some thick thread at the local arts and craft store. At the outlet, loosen the center outlet cover screw a little (no need to pull it out). Wrap the thread a few times around the ac cable near the rear of the ac plug connector. Now wrap the tread around the outlet cover screw a couple times and tighten down the screw...this should offer the support you need at the wall. The same can bo done at the iec end...just loosen the iec socket screws on both sides so you can wrap the thread.

Great idea! Much better than using elc.tape around the IEC end to make things tighter.
Great advice, Alan. Does it need to be a thick thread? Nylon or Cotton? I see a whole shelf of thread at Jo-Ann fabric stores....and I just was there last week looking for burlap for my acoustic panels....:)
I'll try it and report back. By the way, i'm in the US, VA
thanks.
Well how bout that. Didn't think about applying same procedure on iec sockets. I used fishing line to secure the PCs to the back of my speakers. Worked like a charm. Thanks for the idea.
I have this very same problem with my PS Audio lab ll PC's that weigh a ton, 1 lb. of copper per foot x 8 feet, and I have to route them so as to
use their weight to keep them anchored to the floor via 1-5/8" deck screws wound down into the carpet to the underlying cement slab. The PC then lays on the deck screws. With proper routing, they stay firmly attached to my Oyaide SWO-XXX outlet.
This also has a very positive effect on the cable as all the resonances are drained into the concrete.

Thought you might get a kick out of this, but I thought "What the hell are these guys talking about? Their Personal Computers are sagging, maybe it's a computer technique I haven't heard of yet!" . Alright you guys can get back to serious tweak talk now, I'm done being dopey for now!
thanks, Kenster. However, i'm having trouble of picturing what you do here with the power cable. Talking about vibration, should the pc lift off the floor be better than laying down on the floor?
...and all the resonances from the concrete are transferred up into the cable.
I'm just wondering what the perceived benefit is given that mechanical connections are two-way streets for vibration.
Also, I'm assuming the deck screws in use are made of brass or other non-ferrous metal?

"...and all the resonances from the concrete are transferred up into the cable."
U do have a valid observation but my home is built on one big concrete slab and since most of us would agree that something of substantial size/mass will have less tendancy vibrate, or transmit vibrations, then it is safe to say that the relative weight of the concrete slab, as compared to the power cord, will certainly not have ANY influence on the power cord.
Yes the deck screws are Brass but I have used other Deck screws with similar results. U can think of the deck screws as spikes if U will. Why not give them a try on your power cables and report back????

Hi Kenster,
I probably should have asked you what resonances you're trying to drain from the PC.....
By deduction I know you're talking about mechanical resonance, and there are three sources I can think of: from the wall into the cord, from the connected gear into the cord, and from the air into the cord. Are these the vibrations you're trying to soak out of the cord?
One thing you wrote which is not correct is that something massive (and very rigid) will not transmit vibrations. The opposite is actually true. Regardless of mass, rigid materials transmit vibration very effciently. Only compliant materials are poor transmitters of vibration.
So, in your setup you have in essence greatly increased the mass of the cord by coupling it to the concrete floor. In doing so, however, you have also created a fourth path for vibration to *enter* the cord. This means that unless your speakers are effectively decoupled from the floor, you now have a very efficient path for mechnical vibration from your speakers to enter the cord.
Have you tried placing dense, compliant materials between the cord and the screws? Something like thick, soft rubber? This would give the cord the support it needs and would help dissipate virbation between the cord and the floor (regardless of the direction of travel).
I'm definitely not trying to say that you're not getting any benefits from your arrangement, but I am saying that if the benefit is there, it's not because any drain has been created - it's more likely that you've affected any resonances in the cord in a way that improves performance: shorter lengths of unsupported cable would equate to higher resonant frequencies with lower magnitude than longer stretches of unsupported cable.
I would run some experiments myself, but my room/system do not lend themselves to such a setup. I would also question whether my system is resolving enough to hear such tweaks as I've tried some other AC tweaks that seem to work for a lot of people yet make no apparent difference to my system (the Auricap tweak being one in particular).

"By deduction I know you're talking about mechanical resonance, and there are three sources I can think of: from the wall into the cord, from the connected gear into the cord, and from the air into the cord. Are these the vibrations you're trying to soak out of the cord?"
All of the above and also the resonances that are transmitted/picked up through the mains wire that travels from the PD panel, thru the walls, and to the main outlet.
"One thing you wrote which is not correct is that something massive (and very rigid) will not transmit vibrations."
Umm, I never said that. What I did say was that heavy objects tend to vibrate less. The point I was trying to convey was that the power cord can be stimulated to vibrate WAY before the 2000 sq ft./4" thick concrete slab will due to the sheer mass of the slab relative to the mass of the power cord.
"So, in your setup you have in essence greatly increased the mass of the cord by coupling it to the concrete floor. In doing so, however, you have also created a fourth path for vibration to *enter* the cord"
Most of us agree that spikes/cones, or one-way mechanical diodes, are effective at vibration reduction when placed under equipment.
The deck screws have a VERY sharp point and when wound down into the carpet and contact the cement pad, one has effectively made a mechanical diode and the vibrations from the cement pad will not be transmitted with any degree of efficiency up into the power cord or any cable for that matter.
"This means that unless your speakers are effectively decoupled from the floor, you now have a very efficient path for mechnical vibration from your speakers to enter the cord."
My speakers sit on low heavy gauge stands, spiked to the cement, that are sand filled and have my own proprietary vibration transducers attached to the stands. The proprietary VT's are also used on the subs and equipment rack.
"Have you tried placing dense, compliant materials between the cord and the screws? Something like thick, soft rubber?"
Yes I have and it threw a "haze" across the soundstage. Like a camera is slightly out of focus. Just an FYI-I have the deck screws at 12" intervals along the power cords.
I do appreciate your reply and certainly take no offense to it. U R correct in that I am certainly affecting/shifting the resonances in the power cords and I even do the same with my speaker cables to very good effect.
Cheers,

My house in constructed the same way "Slab on Grade".
I am about one block from the freeway.
When a big truck passes on the freeway you can feel it vibrating the entire slab.
I thought it was an Earth quake the first time I felt it.
lol I have similar problem with the Flavor 4s plugged into my active speakers. They are fine unless you bump into speaker or cable and out they fall. Man these cables are heavy. But, they look sooooooo cool coming out of my speakers. lol
