MODEL 560     10 AWG

The 560 is engineered to give full power and smooth full bass response that is clean, detailed, and never bloated. Use the 560 on all your high-current demand gear such as power amps and line conditioners.  The 560 has 312-30AWG pure copper wires and even larger non current limiting dual toroid EMI/RFI noise filtering.  Our toroid filtering is so effective that many customers use the 560 to augment their line conditioners and others no longer need their line conditioners.

These heavy gauge handcrafted power cords give full-powered tight bass response, an expanded 3-dimensional sound stage, and cleaner less sibilant highs.  Vocals will be more dynamic and live sounding because they will no longer be shortchanged with leftover power, or clouded by unwanted EMI & RFI noises from the power lines or your other digital components.

Audiophile Quality Parts.

Finally an AC mains power cord with audiophile grade connectors on both ends.  This is our New Millennium model with super heavy duty WATTaGATE IEC female connector and Hubbell 8215C Hospital Grade male plug on the Models 555, 560, and 520.  The Models 555G and 560G have gold plated WATTaGATE connectors on both ends.  The bare ends of the individual copper wires are treated with ProGold before being secured and shrink sealed into these maximum quality connectors.

Double Toroid  EMI & RFI Filters.

These high power cords are double filtered from DC to 1MHz with proprietary toroidal type filters that have extra high resistance to saturation by heavy current loads.  Since these toroidal filters are non-inline, they don't choke off any of the necessary current to your power supply during extreme music passages.  The filters are at both ends of the cord to filter in both directions.  This will filter unwanted EMI & RFI from your power company lines from getting into the component.  It will also eliminate the noises generated by the component, especially digital sources such as CD & DVD, from feeding back through the AC line to your other equipment.

The 15amp Hubbell & WATTaGATE plugs are UL & CSA approved.  The wires are UL, CSA, & MSHA approved to 600 volts.  The black outer braid is flame retardant and makes these huge cords easier to handle while protecting them from abrasion.  These cords are highly flexible and can be connected to lighter weight components and easily snaked around obstacles.

This great sounding power cord is shipped already 80% burned-in on our custom proprietary Granite Audio Factory power cord burn-in treatment machine, so you can begin enjoying the benefits to your favorite music as soon as you connect it in your system.  The 5 foot and 8 foot cables are in-stock & ready-to-ship.  Any custom length is available on 2 week lead time to allow for fabrication and burn-in.

MIL SPEC materials for reliable super long life.

Strain Relief Shrink - Very flexible and flame retardant.  Meets MIL Spec MIL-DTL-23053/5 Class 1 & Class 3 for low temp flex @ -67F & heat shock @ +482F without cracking, fluid resistance, and corrosion.  MIL-R-46846, Type 5, and UL224 125C, 600V.

Main Structural Shrink - Semi-flexible and flame retardant.  Meets MIL Spec MIL-DTL-23053.  Meets ASTM D2671 for low temp flex @ -40F & heat shock @ +392F without cracking.

ACTUAL CUSTOMER REVIEWS OF
THE MODEL #555 & #560 POWER CORD.



Don, 
What a big difference the
#555 power cords have made on the Martain Logans Sl-3 speakers.  After listening to them over the weekend I've noticed an improvement overall.  The speakers sound a lot more powerful, the bass and midrange a lot clearer.  Another thing I like, the cords are very flexible which makes it easy to route.  Excellent for a heavy cord.  I'm looking forward to power my Sims components with your cords.  I feel I was very lucky to have found a first class company that cares about their product and customers.  I highly recommend your product to everyone or least give Granite a listen. 
Thank You, B.P.  Bloomington, IN.

Dear Mr. Hoglund:
Your power cords have made a believer out of me. I am skeptical about the claims cable manufacturers make regarding their products. I have found that their claims are really over-emphasized and what the consumer is really getting is a better looking, better constructed cable, but not necessarily an improvement in sound. While these first two attributes are desirable, if the product doesn't deliver the benefits purported by the manufacturer, the consumer is not really getting their money's worth.

I was skeptical about the benefits your power cords would deliver, but decided to try them anyway because I believe that some companies really do make quality products that are worth the money in the performance they deliver. One goes through so many mediocre products to find an exceptional product, and Granite Audio power cords are exceptional products.

I was only expecting to get better dynamics from your power cord, but was pleasantly surprised realizing your power cord delivered much more. Dynamics are so smooth and powerful. There is nothing like watching a movie and having the soundtrack or effects go from calm and quite to powerful, devastating, and oh so smooth. Your power cords do really good things to the bass, making this part of the audio spectrum solid and powerful. Owners of Krell, Pass Labs, Boulder, Classe, and other muscle amps would be in sheer heaven with your power cords.

Your power cords also have a dramatic impact on the soundstaging ability of my Proceed Amp 2. The sound stage widened and deepened giving me a more 3-D image. This first came apparent when I was originally feeding my cd player directly to my power amp. This type of set up has gotten an undeserved bad reputation in the audio press, but if they could hear your power cord in this type of system, I bet a lot of minds would change. Even with the addition of a high quality tube preamp, which are known to excel in dimensionality, I find your power cord indispensable.

As equally as important as the quality of your power cords, Granite Audio is a winner in the customer service department. You have been a pleasure to do business with, really caring about what I thought about your power cords. You make an exceptional product at a fair price and care about your customer. You have a top notch company and should be proud of it. I highly recommend your power cords and doing business with your company.
Very truly yours, Michael L.

Don, You are very welcome!
My first #560 is plugged into my amp and directly into the wall. The second #560 is plugged into my lead Richard Gray 400s and directly into the wall. All I can say is WOW! Movies and music never sounded so open and relaxed! There is much greater dynamics, and the system sounds so much quieter now. Instead of listening to movies at 74 volume level on my Meridian, I can now listen easily at 70-72. I can also hear greater decay at the end of strings and much more natural sounding voices when listening to music.
The #560 has bested all other of my power cords ( and I have had many) in my system. I figure I still have about 2-3 more #560's to go. With a new child on the way I'll be adding them slowly to my system however.
Would you recommend a #555 or the #560 for my Meridian preamp? I am currently using a Synergistic Research AC Master Coupler on it.
I forgot to tell you about the video improvements the #560 made to my HDTV. Colors are now richer, and there is increased depth to the picture. This is an addition to what the Richard Grays did for my HDTV.
Thanks again and regards,  Pete

Hi Stephan,
I just wanted to let you know how glad I am with the Granite Audio power cord.  I received it a couple of days ago (thank you so much for your great and quick service!) and it has proven to be nothing short of a revelation in my system.  Until shortly, I have always been satisfied with my Transparent Plus power cords. They were a clear improvement over the standard power cords you get with your equipment and I thought they were the end of my search.  However, after plugging the Granite Audio 555 AC cord into my pre-amplifier, I suddenly realized how much of an improvement I could still gain in my system using better power cords.  In comparison to the Transparent cord, the 555 makes the sound of my hifi system much more open, deeper and wider with more highs (but none of the harshness), more lows and much more naturalness.  It is as if the speakers kind of disappear and the musicians are standing in my listening room.  Granite Audio makes a truly GREAT product here which I would truly recommend to everybody looking for a superb power cord.
I still have to do some serious saving, but once I have the money I think I will replace all of my Transparent power cords by those from Granite Audio!
Thanks again for all of your time and efforts; I appreciate it!
Best regards,  Rainer

I love the Granite Audio #555. For the money it kills a lot of the more expensive power cords.  I've tryed some very expensive power cords. The Granite Audio #555 is my favorite so far and doesn't cost an arm and a leg.

Don,   You are very welcome! I must stress again that getting this $800 demo PC for $XXX was a steal (outright highway robbery!) for the improvements it made to my entire system, especially as it settles more and more into my system. Hell, even $800 would be a good investment for my Meridian based system! Even my RPTV looks better than before (everything is plugged into the same dedicated power line, as I believe more than one line causes feedback loops and raises the noise floor). This is an extra bonus in addition to what the RGPC's have done for me. So the filtering of the #560 is working across the entire line.
I'm now a big believer in unrestricted power flow with the lowest noise floor possible. By the way, I've tried Cardas, Synergistic Research, the Black Mamba, Straight Wire Blue Thunders and Kimber PCs, and the #560 is by far the best I've had in my system!
You can also thank Steve Bruzonsky (I think you know him well) for suggesting your cables. I will certainly be getting more of your PCs in the future.
Regards,   Pete
