Budget esoterica review magazine
June 2014 mini review

Many audiophiles own stereo gear that have detachable power cords. This gives them the freedom to upgrade to their power cord of choice thereby offering them a possibility to upgrade the sound. Owners of stereo gear that have fixed or captive power cords do not have this luxury, however there are still ways to improve the sound. One way is to plug your components into an audiophile multi-outlet strip that is plugged into your favorite audiophile power cord. In my case i plugged in my nad stereo receiver and denon dvd player, both of which have fixed cords, into the audioquest IEC > 3US power strip which i then attached to my Cullen cable power cord. This is probably not going to give you as good performance as if you had hooked up an audiophile power cord directly without the power strip bypass and your fixed power cord, but you should notice some improvement.

The Audioquest mini power strip sells for under $35 and is available at a wide variety of retailers. It allows you to plug in 3 components and claims to use a high-purity copper buss connection. It is a well designed and nicely finished product. In my system it seemed to pass through the signal and power flow without any changes in sonic integrity, and indeed i could hear some of the positive attributes of my Cullen power cord also.

One improvement i heard was a better sense of rhythmic flow.
This was most notable on the Rhythm Of The Saints cd by Paul Simon. I also noticed a slightly smoother sound with a little better sense of liquidity.

While listening to the Boz Scaggs Silk Degrees cd i noticed an improved sense of airiness on track number five and once again the rhythmic flow was very good. There also seemed to be a reduction in muddiness. The highs and mid range may have been a tad smoother too.

One of my favorite Miles Davis cd's is friday night at the Blackhawk, San Francisco. This is a 2 cd set with 24 bit digital mastering on the Columbia label. The power cord tweak seemed to soften up the sound a little bit and made the recording sound a little less harsh. Horns had enough bite without going over the top. On disc number 2, track 5,
if you listen closely you can hear a phone ring twice at around 12 minutes and 47 seconds into the song.

The Audioquest IEC > 3US power strip gives owners of stereo components with fixed cords the flexibility and freedom of choice to use their audiophile power cord of choice. You will then have the ability to receive some of the benefits of an aftermarket power cord with your components. I noticed slight improvements in my system and i think you might also.
For under $35 i consider this a worthwhile tweak. Recommended.

Hi Honda6

I've been using the AQ IEC 3US for a bit now and it is my audiophile extension cord. I have some older pieces of gear with captive power cords so what I like to do is take my audiophile aftermarket power cord put the AQ IEC 3US on the end and then plug in my gear with the captive power cords into it like what you stated in your review. So this way all older gear gets the benefit of the power cord as well s the Audioquest IEC 3US.

Now have you tried using a different power cord with the AudioQuest IEC 3US? Have you found the same results like when you used the Cullen Cable with it?

Sometimes I've used the AQ IEC 3US to aid in the breaking in of new power cords. I'll use the new power cord as an extension cord and plug in all sorts of gear into it to break in the power cord. I'm just careful to not go over the amp rating specified on the AQ IEC 3US.
