"Very Well Balanced" Headphone Amp
The WA6 from Woo Audio is a high performance all-tube headphone amplifier whose big performance belies its compact size. Its hallmark is realistic, warm, smooth sound. The versatile design drives a wide range of full-sized headphones and in-ear monitors. It uses a singled-ended triode, 'Class A' all-tube-drive, output transformer-coupled design.
Unlike many other headphone amps on the market that make partial use of vacuum tube circuitry, but otherwise are solid state designs, the WA6 boasts an all-tube design. There are no transistors, ICs, or semi-conductors anywhere in the entire circuitry.
"Can Make Good Headphones Shine"
"I think the Woo 6 is a great amp that with a good source can make good headphones shine," reports George Chronis in his Head-fi.org review for February 8, 2007. "Very well balanced, very audible difference from my previous setups."
"With a creamy, natural sound and tight bass response, along with pro-grade build quality to match, we're sure any serious music lover would enjoy this fabulous piece of audio bliss," notes ApartmentTherapy.com.
"Overall clarity is excellent, it sounds natural and the sound is clean/undistorted without a morsel of off sound or graininess," says WalkGood in a March 21, 2009 review for AnythingButiPod.com.
Beautiful Inside and Out
The WA6 is a high quality, beautifully made product inside and out that uses point-to-point wiring throughout its construction. It uses a premium custom-made 80-watt toroidal power transformer for quiet, dependable operation. Silver plated wires in a Teflon jacket add to the performance.
The casework boasts an aluminum die-cast chassis with an anodized finish along with aluminum volume knobs and power switch button.
For smooth, rich audiophile performance, you can't beat the sound of vacuum tubes. The WA6's tube complement consists of two 6DE7 drive/power tubes and one 5AR4 rectifier tube.
You get no-nonsense connectivity with your Woo. It provides one pair of RCA inputs and one 1⁄4" stereo headphone jack. A high/low headphone impedance switch ensures compatibility with a wide range of headphones.

"I think the Woo 6 is a great amp that with a good source can make good headphones shine. Very well balanced, very audible difference from my previous setups, clear difference from the Presonus, no noise. This is without any break in at all on my part and stock tubes (except 12 hours that Jack [Wu] said he did)."
