A high-performance, high-end speaker, made in Utah

The Zu Essence is a big speaker, with a really big sound, fully capable of rocking out like few high-end speakers anywhere near its $3,600 price can. The Essence's wham-bam dynamics are explosive, so please trust me on this, you'll never get that sort of impact from a bookshelf or smaller speaker. My complete Essence review appeared in Home Entertainment magazine, but let me share with you the gist.

Speaker design over the last decade has mostly been devoted to producing greater accuracy, higher resolution, lower distortion, and wider frequency response, but those qualities don't necessarily produce a sound that will stir your soul. Accuracy is one thing, but there's an artistry to speaker design no computer will ever match. Zu designers are definitely more interested in musicality than accuracy, and it totally works.

The Essence is 49 inches high and 12 inches wide and deep. It has a 10.3-inch full-range driver and a 2.5-inch foil-ribbon tweeter. The advanced technology tweeter is sourced from Taiwan, and then entirely rebuilt and modified in Ogden, Utah. All of the 10.3-inch paper-cone driver's parts are made in the U.S., and assembled in the Zu factory. The completed tweeters and woofers are extensively tested and sorted into matched, close-tolerance pairs that are used in production speakers.

Zu offers a range of standard painted and wood veneer finishes, and a slew of extra-cost custom paint finishes. Zu's paint shop does outstanding work, with overall build quality the equal of speakers that sell for many times the Essence's $3,600 price. In the context of today's high-end speaker market the Essence is a steal!

This speaker can rock out better than any speaker near its price, and since the Essence is unusually efficient, it clicked with very low-power amps, like the $378 Miniwatt N3 (3.5 watts per channel amplifier). Actually, the speaker sounded best with a First Watt J2 (25 watt stereo amp), but I've also used the Essence with my 400 watt per channel Parasound JC 1 power amps, no problem. In fact, the Essence delivered great sound with every amp I've tried. … Read more

Can a 3.5-watt amplifier rock your world?

Audiophiles never gave up on tube electronics. Sure, there's no shortage of great-sounding solid-state amps to choose from, but tube amps are still a hot commodity in the audiophile world. As good as solid-state amps can sound, they never sound like tubes.

Thing is, tube electronics are more expensive to build than solid-state gear, so when I hear about an affordable tube amp, I want to hear it.

The Miniwatt N3 Integrated Tube Amplifier uses a single ECC83 twin-triode tube feeding a single EL84 output tube per channel, and the amp features a switching power supply. The N3 delivers a healthy 3.5 watts per channel; it was designed in Hong Kong and it's built in China.

Yeah I know 3.5 watts doesn't sound like much, but the N3 made its presence known with a range of speakers, running from my Audioengine P4s ($249/pair), to Dynaudio Contour 1.1s, up to the mighty Zu Audio Essence towers ($3,600/pair). I can't tell you the N3 will work with every speaker, satisfy headbangers, or fill your loft with high-decibel sound. But those 3.5 watts will play louder and sound better than you would have thought. At night with your room lights turned down the tubes' soft orange glow will look way cool. … Read more

$229 vacuum tube amplifier wows audiophiles

If you think all high-end products are stupid expensive or mammoth monstrosities, the MiniWatt vacuum tube integrated amplifier should change your mind. What differentiates high-end gear from mass market technology is performance; mainstream manufacturers know sound quality isn't much of a priority for most buyers, so they build their products to sound just good enough.

By high-end standards at least, the MiniWatt is dirt cheap, just $229 (shipping is $40). And measuring just 5 by 4 inches, the little guy can fit anywhere. Powerful it's not, just 2.5 watts for each channel, but that should be plenty … Read more
