The Entry Level #19 Page 2

As Omar sat in the sweet spot, I quickly swapped the RadioShack zip cords for Kimber 4PRs, made sure the pluses and minuses were properly matched, took my seat, and started "One Armed Scissor" from the beginning. Again, I wondered: What if we don't hear an improvement? I shouldn't have worried. The 4PR's sound quality was just as immediately obvious as its build quality. Five seconds into the song, Omar and I turned to one another. I smiled and nodded. Omar looked pale. He blinked. He frowned. He said, "Wow."

Most apparent to Omar was an increase in overall clarity and low-level detail. "I could hear those backing vocals better," he said. "The sound was muddy before." In addition to that clarity, we both enjoyed the Kimber's tighter, better-controlled bass. Bass is music's foundation; as it goes, so goes the sound. With the Kimbers in Omar's system, there were more subtle gradations of texture and tone in the song's opening moments, the bass now working as a proper anchor to the heavy electric guitars and quickly shifting drum patterns. It all created a sense of swelling, purposeful movement, steady momentum, and enhanced drama—all good things.

Turning back to the RadioShack cable confirmed its much more simplistic overall sound. Unlike the more-nuanced, better-detailed Kimber, the RadioShack served up all the musical elements at the same time, with less regard for tonal color and momentum, creating a less interesting, less involving listening experience—fine, but easily forgettable.

Still using "One Armed Scissor," we compared the 4PR to Kimber's 8VS. All the earlier improvements were there again, but now they were even more dramatic, inspiring Omar and me to dissect parts of the song. At around 2:25, as drummer Tony Hajjar moves from his crash cymbals to a circular tom-tom pattern, guitarists Jim Ward and Omar Rodriguez-López shift from heavily distorted power chords to moderately phased open chords. The band continues in this mode for about 30 seconds before returning to the verse. Through the RadioShack cords the subtleties of this section had been almost entirely lost, and while the Kimber 4PRs had brought those subtleties back to life, the 8VS cables presented them with even greater urgency, drama, and purpose. Those 30 seconds became a memorable and emotionally compelling bridge—exactly what the band intended, I imagine.

We continued our tests using Jay-Z's "The Blueprint2" and Sonic Youth's "Becuz," and the results were similar: improved clarity and low-level resolution; tighter, more musical bass; greater overall enjoyment. "It's like the music gets here sooner," Omar said. And it was around that time in our listening that he opened his MacBook, launched an Internet browser, and began searching for prices of specific lengths of Kimber Kable. I was surprised to hear him say that the 8VS was "cheap" and the 4PR "super cheap," but I guess I shouldn't have been—the quality and value of Kimber Kable's products speak loud and clear.

"I knew this would happen!" Omar moaned. "I'm not gonna be able to go back to the RadioShack cable!"

I badly wanted to laugh. My work here is done, I thought.

Polk Audio RTi A3 loudspeaker
Back at home, however, my work had just begun. I'd recently set up Polk Audio's RTi A3 loudspeakers ($399.95/pair), which, at 14.75" H by 8.58" W x 14" D, are by far the largest bookshelf models I've had in my listening room. Right out of the box, the RTi A3 impressed me with its fit and finish. In Polk's Damped Asymmetrical Hex Laminate Isolation (DAHLI) cabinet design, five layers of MDF are glued together to form a damping system, then topped by a real-wood veneer of black ash or, in the case of my review samples, an impeccable cherry. The gracefully curved cabinet narrows in width from 8.58" at the front to about 5" at the rear, and is said to create a stronger, more rigid, more acoustically inert enclosure. (Knocking on the speaker's side panels resulted in a hollow resonance.) In addition, Polk boasts that the RTi A3's drive-units—a 1" silk-dome tweeter and a 6.5" polymer-composite woofer—are Klippel Optimized and Dynamically Balanced. According to Polk, the former means that the speaker should perform well at both high and low levels, while the latter means that the drive-units have been designed to avoid deleterious colorations. Finally, the RTi A3 uses Polk's Power Port, a system in which two ports—one at the front and one at the rear—work together to reduce noise and distortion for clean, powerful bass (footnote 1).

But would all this fancy-sounding stuff make sense in my room? I was beginning to worry. I knew the Polks were big—wheeling them along Newark Avenue and carrying them up the two flights of stairs to my apartment had been more of a challenge than I'm used to—but I didn't fully appreciate their size until I placed them in my listening room. The Polks completely dwarfed my reference PSB Alpha B1s ($299.99/pair). Would they overwhelm my little (13' by 10' by 8') room? More important, would they look ridiculous? What would girls think?

I shouldn't have worried. Once I'd set the Polk RTi A3s on my speaker stands, they looked surprisingly good. In fact, they seemed right at home, blending in perfectly with my furnishings and lending the entire room a mature, sophisticated look. But what about the sound?

Initially, I connected the RTi A3s to my NAD C316 BEE integrated amplifier ($380) using the Kimber 8VS speaker cable. Source components were my Rega P3-24 turntable ($1295, discontinued) and my NAD C515 BEE CD player ($300). When playing vinyl, I used the outstanding Parasound Zphono•USB phono preamplifier ($349). All interconnects were Kimber's PBJ. I spent some time experimenting with speaker placement, but found that the Polks performed best when placed exactly where the PSBs had been: about 8' from my listening position, 30" from the sidewalls, and 42" from the front wall. I began with the speakers' grilles removed simply because I wanted to expose their pretty baffles.

Over the first few days of listening, everything I played—from Pantha du Prince's wonderful Black Noise (LP, Rough Trade RTRAD LP544) to Ricardo Villalobos and Max Loderbauer's Re: ECM (CD, ECM 2211/12) to Tenniscoats' enchanting Papa's Ear (CD, HÑpna H.48)—sounded unusually lively and present, with fast transients, lots of detail, and well-extended highs. While this sound was exhilarating, it could also be a bit too much to handle. Recordings that are already bold and forward, such as "Ni See Ay Ga Done," from Sidi Touré's excellent Koïma (CD, Thrill Jockey 301), sounded unnaturally fast and detailed—the Malian guitarist's bluesy riffs were granted extra measures of pluck and shine, but were stripped of all their soul. I could soften things up a bit by putting the speakers' grilles in place, but only at the expense of that beguiling presence. Just when I thought hope was lost, I saw the answer right in front of me, neatly coiled on my listening-room floor: AudioQuest's Rocket 33 speaker cable ($299/10' pair). Swapping Kimber's 8VS for the Rocket 33 finally resulted in the best balance of detail and body. I used the Rocket 33 for the rest of my listening.

From the very start, I had expected more bass from Polk's RTi A3, and it certainly gave it to me—but I noticed that increased bass only in direct comparisons with the smaller PSB Alpha B1. The Polk's overall sound was just as tonally correct and well balanced as the PSB's, with clean, clear mids and vibrant highs. What most impressed me about the Polk, however, was its presence and physicality. The larger speaker offered a muscularity, weight, and solidity that made listening to well-recorded rock an absolute, fist-pumping joy. "Road Dog," the second track of Dope Body's outstanding new album, Natural History (CD, Drag City DC513), opens with gently brushed chimes, some well-placed snare hits, and a slowly building tom-tom beat. As that beat grows in speed and intensity, two electric guitars, panned hard left and right, enter with quick raking sounds. The Polks presented each of these elements with startling jump factor and precision, easily turning my small listening room into a hot, crowded basement in the suburbs, with 50 or so sweaty teenagers jostling for a space in the mosh pit. The effect was extremely physical and compelling. The PSB Alpha B1 lacked the Polk's oomph and scale, and just couldn't infuse "Road Dog" with the same frightening presence and power—a shame.

For years, I'd thought that a good minimonitor speaker with a 5.25" woofer was all I'd ever need to fully enjoy music in my small listening room. But after hearing the Polk RTi A3, with its 6.5" woofer and Power Port Plus and all that other stuff, I'm not sure I can go back.

Damn. Now I know how Omar feels.

Why oh why can't we get measurements with these cable reviews? We get measurements with speakers, audio and video components etc but not cables. I still say if cable A is better than cable B it should be easy to show performance numbers.. I can only hope and dream..

Better than numbers, I gave you words.

I'd take real collected data that can be readily reproduced via documented experimentation over a pompous idiot's BS any day. But perhaps that's just me. Talk is cheap. Total BS is worth less than talk.

I've always liked Polk Audio, I own a nice pair of LS50s, bought when I was 21 in 1992

Measurements are one way to evaluate components, and your desire for a way to generate a straightforward and objective evaluation makes perfect sense. I'm the wrong guy to engineer that equipment however. Thirty or more years ago, manufacturers got enamored with amplification measurements and produced some really execrable receivers and amps.

When the original article on using twisted pair Radio Shack wire for speaker cable came out in Stereophile, my listening buddy and I figured we could do a cheap test on our own. A spool of red and black might have cost a total of $ 10. Subjective yes, and perhaps not 100% normalized, but we spent an evening doing blind A/B comparisons and sipping our preferred beverages. Both of us could easily tell to which cable we were listening.

Stephen, I had an opportunity to pick up a 3.5 mm m/m cable for my traveling kit at Radio Shack called Auvio. Sounds great, perhaps you could do a review. Certainly is priced right.


Best, Fran

Hi Fran. That's twice this week that someone's mentioned the Auvio cables. I'll have to check them out. Thanks.

Thank you for a great review of the Thinksound ms01 and for pointing out such a great sounding and affordable set of portable headphones.  As a long time Klipsch s4i user, I enjoyed my headphones a lot but knew there was just "something" that was not 100% right with them.  I had noticed the harshness but always thought it was the fault of my rips or settings, but, with your review you hit the nail on the head for me.

I generally am not an impulse buyer, but within a day of reading your review I was online ordering not only a set of ms01's, but also the appropriate Comply pad upgrades (I'm a distance runner and use these for long multi-hour runs and bike rides).  I could not be more pleased, the harshness from the songs is gone, the phones are much more enjoyable to listen to for extended periods, and the Klipsch units have now been relegated to my cube at the office to block out the sounds from the rest of the staff, in a definite non-audiophile setting.

Thank you again for findings such great products to review and profile and I look forward to your continuing sagas and stories.

Here's the problem: two pieces of wire linking an amplifier and a loudspeaker and delivering AC of varying frequencies are doing a far more complex job than two pieces of wire delivering 6 volts of DC from a battery to a lightbulb.  You can easily meausure the properties of the cable in the latter situation: inductance, capacitance, resistance but those same measurements will vary widely with so many variables on either end of a cable between an amplifier and a loudspeaker. 

Sadly, it really is "cut and try" when it comes to audio cables . . . either interconnects or speaker cables.  And, to the extent that static measures can be useful, it seems that high inductance on a loudspeaker cable is not good, but high capacitance is o.k. but high capacitance on an interconnect is not good; but high inductance is o.k.

Even to these "rules" there are lots of exceptions, sadly, for the buyer.

mrplankton2u's picture

Amplitude, phase, and frequency data can be very precisely measured at the input and output ends of any cable - precisely establishing the effect or lack thereof produced by the cable. Electricity maybe magic to a total newbie or a fraud who's bent on establishing a scam. Inductive, capacitive, and resistive phenomena have been studied ad nauseum. There is no mystery. No magic. Anyone who insists that there is is either a complete fraud or a moron. Take your pick.

Well this could be easily settled: there must be measurements since these smart engineers who manufactured the better cable created it, no? And since they even went into designing a series of cables at various prices, it must be easy to simply ask the manufacturer for their comparative designer sheet.laugh

i can appreciate why some people get all geeked out over numbers, stats, measurements, etc. most equipment can be measured by these. I enjoyed the columnist's article and insight about speaker cable (as well as some posters: very useful info). sometimes you just need to listen to the music....and not over analyze everything. or you can be a pompous, insulting blowhard. whatever works i guess.

what was it about the Rocket 33 that made them a better choice for listening to the Polk  RTi A3? 


Stephen Mejias's picture

The Polks could sound bright, forward, and edgy.  The AudioQuests' darker, fuller sound tempered those characteristics of the Polks, while the Kimbers' greater clarity and control tended to enhance the Polks' brightness.

I`ve read over and over the debate about cables, their high prices, snake oil-like claims what with all the talk of dielectric noise cancelling, gyroquad veristrand and field geometric technologies. Or whatever.

I noticed a set of fancy looking interconnects at a friends house set aside from his system, and he told me he wasnt using them anymore as he upgraded to some other cables (I later found out, Kimber) he offered me his old ones to try out before he put them on e-bay (Audioquest Jaguars 24v DBS XLR`s) and when I say fancy, they were a jacked up looking green color with a battery pack attached to them. Ridiculous looking, I laughed at them but decided what could it hurt to plug them in.

I connected them to my own system and noticed a big difference right away and could not believe it, not just that there were any difference at all but that the difference was very audible. It had more "musicality" and for the first time ever, I now  truly understood the meaning of that word.
I checked all of my settings and other connections thinking I`d find some other explaination of what was happening, but realized after a quick return to those stock cables that it was indeed, these cables named after a cat.
I must have done 5 or 6 a/b comparisons before coming to that final conclusion.
I stood back and listened dumbfounded. "Hello kitty" .

I`m glad I never participated in those sometimes heated discussions regarding cables as I`d be eating my words and passing out apologies now.

Apparently my system has the "synergy" which makes it more susceptible to these audible changes to my equipment.
I see this as both a blessing and a curse. It has introduced me to higher levels of musical enjoyment, but it will also turn me into "one of them guys" who wonders about upgrades and then goes off to spend significant amounts of money pursuing that "next higher high" of musical enjoyment and justifying it by pointing out other things people blow money on.

The kittys are sitting in a cabinet now, a new set of Kimber Heros currently burning in and settling very nicely ...........just as the "cable people" said they will.
