Was it the one titled Read this, and pass it on.... it works? Or the one with the attachment that I'm supposed to "give advice" about?

Just kidding...I just looked for it, but couldn't find it in my in-box. Will you kindly send it again?

rebirth

Hmm, time to revive an old thread

So Jude, did you ever get around to compare that power cord with the stock cord?

chych,

Admittedly, with work being quite busy lately and all, I haven't done the power cable swap. I will at some point, as I'm curious myself. I've been busy enough that my post count over here has been lower than usual too.

On household recepticals, most only have a single contact with the ground pin, and it contacts the bottom of the ground pin...

I checked the receptacles on my Brick Wall, and they all have side contacts for the ground (looks like a bottom contact too). Then I checked my cheapie (came-with-my-house) receptacles, and they all appear to have side contacts (and bottom ones too). Though I don't doubt that some only have bottom contacts for the ground pin.

I had some discussions with the biomedical technologist their, and they said that the warnings were on all the equipment mainly for liability issues, since they hospital grade recepticles are less likely to fail in life/death situations... So i'm not sure if there really is a danger if you use the hospital grade stuff on ordinary plugs, even though most seem to have a different design...


But i'd just like to point out, hospital grade stuff isn't designed to be better conductors/more noise proof, they're just super durable to withstand the wrath of pissed-off nurses...

for Jude

Hi Jude:
YGEM, please I would like to know your comments about that!!!

I'm still very interested in where you guys think these things rank. I have 3 DIY Ven Haus power cables thanks to a capable Head-Fi DIYer. Other than that, everything in my house uses cheap IECs and Monster interconnects. My next major planned "upgrade" is to replace every single interconnect and every standard IEC in my home with something better. The front runner for the interconnects are the Outlaws and so far these Quail power cables seem like the right solution.

(Note: Some day, when my system is further along I'll buy better interconnects and power cables for the sensitive items like the CD player and power amp, but right now I'd like to get everything "above crap," including even the PC, PC monitor, etc.)

green dot, why not the shielded version?

Hi Jude or whomever had use the Quail power cord:
I have a question for you guys, since maybe some of you had use the Quail green dot that I'm planning to use on my MGHead, but searching on the Quail website I found also a shielded version of the cable 14/3, even when not hospital grade, is the same AWG and configuration that the green dot, what makes you select the green dot instead of the shielded, even when shielding may block RFI interference? Or is not enough with the shielding they offer, why then the green dot and the ferrite, is there anything special in selecting one or the other, please could any of you explain me a little bit about that, which are the differences between them? BTW how you get in touch with them? I tried two or three times by email but seems that nobody answers there, not even Katherine, is there any other person whom I have to contact to for just one cable or two, or maybe a sample, I know they use to sell large quantities, but I just need one or two.

good to see some decent budget stuff getting some recognition these days.

Here is a thread I posted about quail power cords a while back:

http://www.head-fi.org/forums/showth...threadid=14048

Should be helpfull. I compared it to one of the kimber cords (can't remember which model)

I can't justify spending over 100$ on power cords, unless my components costed over 2500$ each. Frankly, i'd rather get a 10$ power cord that offers almost just as much improvement, and spend the other 90$ pampering my phono cartridge.

shielded vs hospital grade

shielded vs. hospital grade redux

In my mind, the shielding is there to keep stray RF from reaching components *outside* the cord, not to necessarily protect the power cord itself. But in any case, a well designed power supply should already filter out unwanted AC line noise...

Checking the Marinco website (the maker of some widely used hospital grade and industrial plugs), the green dot gets you the following:

Abrupt plug removal (parallel to wall) test
Ground pin retention tests
Fault current tests
Terminal strength test
Face impact test
Ground contact temperature test
Ground resistance test
Assembly security test
Mold stress relief test
Crush test
Cord grip strain relief tests
Static cord pull test
Rotary cord pull test

That being said, if you still want 'green dot' certification and shielding, why not go DIY? Someone previously mentioned the Chris VenHaus design - the Belden cable used (83802) is a 12 AWG two-conductor cable with a foil and braided shield capable of delivering 25A and handling 300 V RMS. Wind a grounding wire around the outer jacket, stick a pair of Marinco plugs at the ends and you've got yourself a great power cord (I have one powering my Heart CD6000 right now). The only drawback is that it'll cost more than $10...

Hey, Jude... now that you've had them for, what, a year is it?, any "first impressions"?

(I know you take your time when doing reviews. But this is a bit excessive )
