  足球开户赠送体验金58High-end sound gets truly portable with the Woo WA11 headphone ampHigh-end sound gets truly portable with the Woo WA11 headphone amp Woo Audio has been making exceptional tube electronics in New York CIty since 2004. So it came as a big surprise when I received the companys first solid-state WA11 Topaz headphone amplifier. Better yet, its small enough to be truly portable -- Woos taking high-end sound to the streets!Even without the aid of tubes the WA11 ($$1,400) sounds velvety-rich, powerful and refined. Instruments and vocals surely have a lot more body and substance than what I hear from my iPhone 6S headphone jack.The WA11s black anodized-aluminum chassis feels solid, and measuring just 6.1 by 3.3 by 1 inches, its small enough to fit into a jacket pocket. The included Alcantara travel pouch protects the WA11 from scratches. Upfront theres a machined metal volume control and two headphone jacks, a standard 6.3mm jack and a 4.4mm Pentaconn jack(for headphones fitted with balanced cables with Pentaconn connectors; only one headphone can be plugged in at a time). The amplifier circuitry is fully balanced from input to output.Too bad Woo didnt also squeeze in a 3.5mm headphone jack, but space is limited. The amps side panel has a high\/low gain switch for compatibility with easy- and hard-to-drive headphones.The rear-end hosts two USB Type-C ports, one for data, and one for charging (its only USB 2.0 compliant) so you can listen to the WA11 and charge its lithium-ion battery simultaneously, or listen for up to six continuous hours of battery-only playtime. The WA11s built-in ESS Sabre Reference digital audio converter offers high resolution playback up to 24-bit\/384kHz PCM files and up to DSD128 for DSD files. At home, the WA11 can serve as a dandy desktop USB digital audio converter\/headphone amp. Its compatible with PC, Mac, Android and iOS devices. I had good results on my desktop with my Mac Mini and also with my iPhone 6S.Theres one other bit of connectivity, a 4.4mm Pentaconn stereo analog balanced audio input, but no analog outputs so the WA11 cannot be used as a preamp. Maximum power output is specified at 1.2 watts per channel for 30-ohm headphones. Wowed by the Woos soundI paired the amp with a wide range of headphones, starting with something truly special, the Audeze LCDi4 in-ear headphones. Wow! The sound was lush, clear, and very low in distortion. Ive always loved these phones, but they never sounded this organically rich before. The Sennheiser IE800 in-ears, one of my long-term references, were also very appreciative of the WA11s talents. I play the IE800 with my iPhone 6S all the time, but here with the WA11, the sound filled out with no loss of clarity. I was eager to try the WA11 with the extraordinary Abyss Diana Phi on-ear headphones (review to come). The purity of the sound took my breath away, but this wasnt the sort of uber-transparency that highlights the faults of everyday recordings. The sound was sweet as can be, and stereo imaging was expansive.The WA11 did stumble with the Diana Phi when I played the Isle of Dogs soundtrack album really loud. These are power-hungry phones after all, and battery-powered amps struggle to keep up with the scores big bass drums. With less challenging music, the WA11 sounded great via the Phi, while the Hifiman HE1000v2 headphones excelled with the WA11 on the Isle of Dogs massive drum thwacks. I also tried my AKG K812 over-the-ears, which are among the most open sounding headphones I own. The K812 can sound a bit lean, but the WA11 brought more warmth to their sound, a welcome change. To finish, I hooked up my Schiit Yggdrasil digital converter to the WA11s Pentaconn analog input. But as good as the Schiit converter is, I preferred listening with the WA11s built-in converter! Which is how I suspect most WA11 buyers will use the amp. The Woo Audio WA11 Topaz demonstrates extreme high-end sound in a portable size is possible. At least for audiophiles whove already invested in top-quality headphones they would like to enjoy on-the-go, at home or office. Wherever you go, the WA11 will bring out the best in your headphones.
