Conrad Johnson 17LS Power Cord Recommendations


I just added a CJ 17LS pre to my system and wondering if anyone can offer their recommendation/experience on which power cables match up well with the unit.

I currently have the unit hooked up with a Signal Cable power cable and the rest of the system is a combination of Signal Cable and Harmonic Technology power cables. All the interconnects and speaker cables are Harmonic Tech.

The unit is sounding a little "restricted".

As always - thanks for the help.

Clayeton, what power cord came with the 17LS? The reason I ask is that I tried several different PC’s with my CT-6. The factory PC that came with the CT-6 had what CJ calls their “hospital grade” cord. At least I think that is what Lew Johnson told me they called it. It has a ‘clear” plug. When I switched to a Premier 16 the aftermarket cord I was using with the CT-6 automatically went into the 16. After seeing your original post a couple of weeks ago and remembering that several people on A’gon have already commented that aftermarket cords did not make a difference on their CJ preamps, I plugged the CJ hospital grade cord back into my 16. Voila, the factory cord actually sounds much better, particularly in the mid to upper ranges. Moral of the story, don’t discount the factory PC. If your 17LS did not come with the hospital grade cord, you may want to order one from CJ and try it on for size. I don’t know the price of the cord, but it has to be cheaper than some of the crazy prices people (including me) are paying for aftermarket cords.
I've tried a various cords on both my 17LS and now
my CT-5. My two favorite cords were the BMI Hammerhead
MK3 and a Tek-Line Reference. The MK3 cord is harder to
find these day's and its more pricey than the Tek-Line cord
as well.

I believe Tek Line will let you demo the cord for 30 days so
you have nothing to lose.

Good luck

I have found the BMI MK5 power cord to be the most unristricted cable I have heard to date. I would be completely stunned if this cable did not make a difference over any stock cable on the CJ's.
I have a 17LS2. I tried a Shunyata CX cord, which made the sound brighter and edgier. In the end I went back to the stock cord- more natural sounding, less fatiguing.
