Mini Review: Triode Wire Labs “Seven Plus”


I met Triode Pete of Triode Wire Labs at CAF this year. Happily, Pete sent me a trio of his power cords, a pair of Seven Plus power cords and one Ten Plus. The numbers don’t refer to anything other than wire gauge, so keep it in your pants, Sparky. Anyway, I’ve had a lot of fun — and no little amount of frustration — playing with them for the last month or so, so I thought I’d take a few moments to share.

The Seven Plus is Pete’s heaviest gauge offering, and maybe one of the heaviest wires that I’ve seen or heard used in a power cord. Interestingly, they’re not at all what I expected. Okay, that’s not true, they are what I expected because I’ve had a chance to wing one of these around my head like a morning star prior to actually getting one in-house, but I’m quite sure that you, gentle reader, will be surprised to learn that this are the most flexible power cords I’ve used to date. Really! The wiring includes the insanely big conductors, but the wire itself (a proprietary metallurgical blend), is as flexible as a striking snake. Absolutely no issues getting it into a space Houdini might find challenging and no weird twisting required in order to orient the connector and no levitation of light-weight components. This is really user-friendly stuff.

The price appears to have been recently bumped a notch, but $499 for a wire this big isn’t outrageous. Pricing for the Ten Plus starts at $329.

Okay, so what’d I hear?

Big Bass and Big Tone.

If you’ll recall my recent comments about wire, generally, you’ll understand where I’m coming from here. The Seven Plus is one of those evolutionary cables that takes the performance of your already-audiophile-grade power cords (come on, it’s not like you’re using the stock cables) into a particular direction, in this case away from a “solid-state sound” and toward a richer, warmer, fuller sound. Not like a Rubenesque transition or anything, but compared to the $199 Nordost Blue Heaven power cords I have, the Seven Plus is smoother and fuller through the entire frequency spectrum, and includes a welcome bass roundness and more capable handling of the lowest frequencies.

EditorsChoiceSmallIn short, the Seven Plus is the best power cord that I’ve heard in my system to date.

Piling on: when used with my amps, the big Plinius SA-Reference, my “Klaus Special” monoblocks from Odyssey (now with 300+ hours on them), or even the amp-direct input on my Luxman L-505u, the Seven Plus had something both useful and helpful to say (if you will). The music took a few small, but audible, creeping little steps toward 3-D (or 4k, depending on how up your are with TV tech). Tone density, saturation, and sonic richness — all took a clear step up. Now, it’s not a huge step up, but it was a step up. Again, recall my comments about the incrementalism of cable contribution. Unless your current cables are actively doing something wrong, the deviations from one cable (or even from one cable family) to another will and ought to be subtle. Anyway, the Seven Plus is unusual, in that it does seem to “do more” down low than even a Nordost cable — something I didn’t think was possible.

I have a lot more listening to do, obviously, and I’d like to do more comparisons with the Ten Plus — as well as with the other power cords I have here. But for now, I’m pretty satisfied.

Winner-winner, chicken-dinner!

  1. HMMMmmmm the MG Speaker cables are close to if not the best I have heard, I would like to try the Triode “7s” against the Less Loss Power Cables. But most trials are not possible or reported in this type of forum. Any way thanks for introducing us to a new power cord company!

      • I did en still do. The Lessloss Signature is a very good powercord in a sense that is produces a wide stage, a very relaxed sound, lot’s of detail. In fact maybe the cord’ that is not there’. But the TWL 7 plus has much more PRAT, more analoque feel, a better low end, more tonal richness. It might function as a tone control, but for me it makes the music more musical, more lively, more real. As with all components, you have to experiment with different configurations (interconnects, powercords, loudspeakercable plus the few tweaks everybody uses….). I found the TWL 7 plus one of the very best cords i heard in a very long time and i am sure it can sound even better with other connectors. On top of that is Peter a very communicative, friendly and decent guy who stays away from the insane marketing and other hi-end bla bla and offers a very good product for a normal price. Happenly there are more out there: Grover Huffman and John Prator are other examples.

  2. Subtle changes from cable to cable signify a less transparent system and hardly a reference to be used for review purposes

  3. Some cables you should check out: MG Audio Design, Downsize Audio Cables. Both companies are using wide copper ribbon speaker cables, and I think they are on to something compared to typical multi-conductor round cables.

    The Downsize power cord is superb, and the silver/gold cables… look out. Spooky good. Think Siltech Royal Signature at 1/100 of the price.
