It's built around a single-ended, all-tube Class A circuit. Three tubes handle amplification: two subminiature 6S31B power tubes and one 6021 driver tube. All three sit visible through a Gorilla Glass window on top.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThis isn't a hybrid design with a tube stuck on for looks. Every stage of amplification runs through genuine vacuum tubes. A rechargeable lithium-ion battery powers the whole circuit, good for up to four hours of continuous playback.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAn ESS Sabre DAC handles digital decoding up to 24-bit\/384kHz PCM and DSD256. The anodized aluminum chassis comes in black, space gray, or gold. It ships in a Pelican hard case for travel.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eSwitchable Tube Count, Desktop-Level Output\u003c\/h2\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eA rear switch lets you run the WA8 on two or three tubes. Dropping to two tubes extends battery life and changes the amp's character. Running all three brings the fullest sound and output.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eIn three-tube mode, output power reaches 250mW into 32 ohms, 350mW into 50 ohms, 180mW into 120 ohms, 120mW into 300 ohms, and 80mW into 600 ohms. Both 1\/4-inch and 1\/8-inch headphone jacks are provided, covering headphones from 8 to 600 ohms.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAn asynchronous USB Type-B input handles digital sources. A 1\/8-inch analog input accepts a phone, DAP, or other line-level source directly. The unit can keep playing while it charges. A long flight or listening session doesn't have to mean downtime.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eCustom nickel-alloy core output transformers round out the internal build. It measures 6.69 by 3.6 by 1.69 inches and weighs 2.4 pounds, closer to a compact desktop amp than a typical portable.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eWhat Reviewers Are Saying\u003c\/h2\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eLieven Vranken reviewed the WA8 Eclipse for Headfonia in June 2016. He wrote that \"if you would let ten people listen to the WA8 without telling them it was a small transportable tube amp, at least eight would think it was a full sized desktop unit.\"\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eHe found that switching between two and three-tube operation \"has quite the impact on the sound as well.\" That gives listeners real flexibility, rather than a single fixed voicing.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAmos Barnett reviewed it for hear.audio in August 2016. He described \"its warm sound signature\" as \"so pleasant to listen with\" across several different headphones. He noted that its DAC section \"pushes detail up into your face, which balances out nicely with the warmth of the amp.\"\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eWho Is This Amplifier Best For?\u003c\/h2\u003e\n\u003cul style=\"margin:0 0 0.9em 0;padding-left:1.4em;line-height:1.6;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eListeners who want genuine tube sound on the go.\u003c\/strong\u003e All three tubes sit in the actual signal path, not as a marketing accent on a solid-state circuit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOwners of demanding, hard-to-drive headphones.\u003c\/strong\u003e Output up to 350mW and support down to 8 ohms cover most dynamic and planar headphones.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnyone who wants both a DAC and headphone amp in one unit.\u003c\/strong\u003e The built-in ESS Sabre DAC accepts USB directly from a laptop or compatible source.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListeners who want proven, independently reviewed performance.\u003c\/strong\u003e Two named reviewers at established publications praised its desktop-level sound in a portable chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYour headphones end in a balanced plug\u003c\/strong\u003e — the WA8 fits 1\/4-inch and 1\/8-inch jacks only, so plan on a single-ended cable or an adapter from our \u003ca href=\"https:\/\/www.audioadvisor.com\/collections\/headphone-accessories\" style=\"color:#8a5a2b;\"\u003eheadphone accessories\u003c\/a\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eHow Does It Connect to Your System?\u003c\/h2\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eConnect a laptop or compatible digital source to the WA8's USB input, or run a cable from a phone or DAP into its 1\/8-inch analog input.
