I too am looking for a power cord for my line conditioner so its power cord upgrade time. I'd not heard of the Kaplan PC's before this thread so I contacted the distributor (Tweek Geek). In particular I want to know how the Kaplan compares to Audience and Synergistic Research Tesla.
This was what Tweekgeek had to say:
In general my impressions are:
The Kaplan cables are excellent, I would liken the filtered cords to an Audience Adept response combined with a power cord. The standalone cord really has no competition at its price point of $349.
The filtered cords come in a 3 amp source/pre and 15 amp high current versions. The 3 amp cord actually has double the filtration for more RFI rejection and lower noise floor.
The cords present a relaxed sound, with a layered mid range, deep bass and smooth highs. Soundstaging is very nice. No listening fatigue whatsoever with these cables.
The Audience Power Chord is not as smooth on top as the Kaplans. If you paired an Audience Power Cord with an Adept Response conditioner, you might be getting close to the sound of the Kaplan Cable, but you would be spending a lot more money.
With the Synergistic cables, its hard to say. Synergistic cables work their best when the entire system is Synergistic. They are meant to work that way, as the sum performance of an entirely Synergistic system is more than the individual contributions of each Synergistic cable by itself. I would say you could compare a filtered Kaplan cable to a Synergistic T3 (if you were going to use the cords on an amp).
When you are using only one or two Synergistic cables in your system, its really hard to predict how they will stack up.
Question: Has anyone compared SR Tesla T3 to the Kaplans when powering a line conditioner? Also has anyone ever tried a Tesla power cord and liked it enough to purchase without running all Telsa power cords? What about the Audience PC, are the Kaplans really that much smoother and if so, do they retain detail and air?.
I intend to do a side-by-side comparison but would like feedback from anyone with experience.
