It's a strange feeling, sitting down to review high-end cables as the sound of children jumping up and down and screaming in a huge inflatable device reaches me through one set of open windows, while music and the scent of grilled food waft through another. You never know what you'll encounter in Oakland's barrio, except on Labor Day, when it is inevitably noisy and hot.

Even noise has its advantages, however. As I hear my wonderful neighbor, José, rap away in a voice much too loud for comfort, I'm reminded of the true timbre of voices. As overly-wired Buicks and Oldsmobiles drive down the street with what passes for sound systems screaming, and as fenders rattle and birds are silenced – I am not making this up – I remember how many people raised on electronic music have no idea what natural as opposed to overly bloated, out-of-control bass sounds and feels like.

All of which leads me to Nordost Tyr. Until Nordost recently announced the arrival of their $14,000 Odin interconnects and $20,000 Odin speaker cables, Tyr occupied second place in a Nordost cable hierarchy crowned by Valhalla.

But once Tara Labs came out with a set of $15,000/pair interconnects that caused some reviewers to rave, and many, many sets of eyes to bug, you could be sure that Nordost would follow suit (and at $1,000 less for a set of top-of-the-line interconnects).

The Design

All high-end Nordost cables contain silver-plated copper solid-core conductors. In Tyr's case, we are talking 60 microns of extruded silver over 99.9999% OFC. Tyr interconnect conductors have four 24 AWG solid core conductors, while the speaker cables have twenty.

The Nordost Valhalla power cables and Tyr interconnects boast dual mono-filaments arranged in what Nordost claims are "Optimized Arrays." Both Tyr and Valhalla interconnects and speaker cables surround micro mono-filament spiral spacing with extruded Teflon (Fluorinated Ethylene Propylene - FEP) insulation to create a virtual air dielectric.

Nordost's combination of materials and construction is said to eliminate conductor strand interaction, and reduce the audible distortions cause by skin effect and magnetic field interactions (some will claim that the skin effect does not involve frequencies in the audible band).

Very precise conductor spacing is used to keep capacitance and inductance extremely low. Nordost claims that micro-mono-filament technology increases signal bandwidth, resulting in cables that transmit signals at over 90% the speed of light. They have said, "This is 20 to 25% faster than conventional cables, resulting in a tremendous improvement in musical accuracy and clarity."

Yes, yes, I know that doubting Thomas's out there will say this is all nonsense, and that all cables sound the same. So, go use your 16 gauge lamp cord speaker cables and leave us to our own devices here. We have a right to our opinions too.

Tyr speaker cables in particular share many visual similarities with their shiny, silver big brothers. Examination combined with a rare skill at higher mathematics reveals that Tyr has half as many conductors, and that its conductors are spaced farther apart than Valhalla's. Both lines of interconnects are pretty flexible – Tyr more so – while their Flatline speaker cables easily curl around corners.

The Sound

What matters most, of course, is the sound. Much has been written about the sound of Nordost Valhalla in these and other pages. With live music serving as my reference, particularly as heard from prime orchestra seats in Davies Symphony Hall (San Francisco Symphony), as well as the War Memorial Opera House (San Francisco Opera), Valhalla has brought me closer to the sound of live, full-range music than any other cable I've tried in my system. Its clarity and transparency are extraordinary, as is its ability to convey the presence of instruments and voices without altering timbre in any way.

Because Valhalla cable is so fast, I never have the sense that attacks are delayed or softened, or that a romantic haze has settled over the music. Nor do I feel that detail has been compromised or smudged over for the sake of smoothness. Valhalla is an extremely honest cable that neither prettifies nor beefs up sound. It may not deliver the fullest sound possible at lowest frequencies, but unless one's room, speakers, and system are absolutely dialed in to deliver huge amounts of bass without booming, a little less bass usually translates into more of a good thing.

It would be nice if you could get the same detail and transparency from other top-of-the-line audiophile cables as you can get with Valhalla. Sadly, that is not often the case. During my last visits to the Rocky Mountain Audio Fest and CES, I encountered a number of systems wired with a certain well-known brand of cabling. (Until I hear this cabling in my reference system, I am not comfortable mentioning its name). As I made mental note of what I was hearing, I began to discover a common sonic signature: large blocks of colorful sound, lacking ultimate top-end extension and detail. If this cabling were used with speakers or electronics that were in any way tipped up or tizzy, or with lower quality front ends that tended toward a bright, metallic presentation, it did a wonderful job of smoothing things over. Everything sounded beautiful, to a fault. No wonder some manufacturers prefer it for their demos: it brought out the beauty of music while masking the limitations of their equipment.

Tyr and Valhalla are another case entirely. Both cables reveal rather than mask. After using Tyr for months in both our upstairs secondary system and downstairs reference system, I'm convinced that it delivers virtually all of Valhalla's clarity, transparency, and neutrality. Indeed, when it comes to sparkling openness on high, lightning-fast presentation, and soundstage width and depth, I would be hard pressed to differentiate between the two.

Take one of my favorite recordings, "Entre Amigos" featuring bossa nova vocalist Rosa Passos in duet with bassist Ron Carter (Chesky). With Tyr, every half-voiced whisper of the insinuating Passos comes through beautifully, as does the musicality of Carter's acoustic bass and the fullness of the guitar and other instruments. I've played this recording on my Nordost-equipped system for countless audiophiles. In every case, they have surrendered to Passos' vocal beauty. If you have an excellent system, Tyr can make you feel as though you're right there in the recording studio, with Passos purring directly at you.

While switching between Tyr and Valhalla, I wrote CD reviews of vocalist Valerie Joyce's New York Blue (Chesky), the Tord Gustavsen Trio's Being There (ECM), and Mozart Sacred Vocal Music (Covello). I loved the sound of both cables, and could hear no major difference in presentation save for one area: bass. When it comes to bass and lower midrange, the differences between Tyr and Valhalla interconnects and speaker cables seem roughly analogous to the difference between Valhalla and Vishnu power cords. The Valhalla consistently delivers more full range sound.

Take the Chicago Symphony Orchestra's superb recent release of Mahler's immense Symphony No. 3. Boasting one of the longest first movements in the symphonic literature, plus a memorable "Urlicht" section sung by a mezzo-soprano, Mahler's Third provides a major test for an audiophile set-up.

Valhalla enables me to hear CSO's timpanis pounded to their limit, and double basses sawing away at fortissimo levels. Tyr certainly transmits the sound of those instruments, but not in as full a manner.

A Matter of Importance

What's most interesting is that, had I not initially heard Mahler's Third performed live in the concert hall, I might not have realized that Tyr did not convey timpani and basses with all the fullness and force of the live experience. Why? Because Tyr's sonic presentation is so colorful, transparent, and alive in the moment – so musical – that I was far more taken by the beauty I was hearing than distracted by what was lacking.

The manner in which Tyr satisfied reminds me of the joys provided by many bookshelf speakers. While organ and home theater DVD enthusiasts might only be happy with full-range floor-standers augmented by high performance subwoofers, many audiophiles are content with bookshelf or stand-mounted speakers that do not extend below 80 Hz. This is because the sound they deliver over most of the range is so musically satisfying.

Musicality is the key. Here's an example. Last night, the spouse and I spent a spellbound few hours watching La Vie en Rose, the cinematic biography of chanteuse Edith Piaf. For anyone who has heard it, Piaf's voice is as recognizable as Billy Holiday's. First there's its husky, resilient quality, the sound of someone who declares I am here no matter what. Then there is the masterful use of vibrato, which she employed at the end of phrases to give her declamations a unique singing quality. Finally, there was a disarming flow to her singing that non-musical voices cannot reproduce.

Tyr is so musical that fixating on the question, "Is the glass half full or half empty?", misses the point. Tyr has the astounding ability to reproduce musical events as though there is hardly any cable between you and the real thing. Its speed, openness, and neutrality set it apart from the pack.


Tyr interconnects and speaker cables maintain Nordost's reputation for lightning-fast, transparent sound. Beyond their estimable neutrality of timbre, they convey the soul of music as few cables do. Although they are neither the fullest nor richest sounding cables on the market, their openness and clarity are instantly endearing. Depending upon your listening preferences, they are a must-audition.
