It is a\nsingle-ended triode, Class-A, all-tube design, transformer-coupled at the output. There are no\ntransistors, integrated circuits or semiconductors anywhere in the circuit.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eSplitting the design across two chassis is the whole point of the SE. The transformer\nand its filtering sit in their own die-cast case, well away from the audio circuit, and the\nresult is an amplifier with a very low noise floor for you to listen past.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eTwo 13DE7 driver and power tubes do the amplification, with a single 5U4G handling\nrectification. Woo moved to the 13DE7 in April 2017 for the second generation. First and\nsecond generation tubes are not interchangeable, so buy for the one you own.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eBuilt by Hand in New York\u003c\/h2\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eEvery WA6-SE is wired point to point rather than laid out on a circuit board. A custom\n80-watt toroidal transformer feeds the supply, and each channel gets its own filter choke, so\nneither side borrows current from the other when the music gets busy.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eSilver-plated wire in Teflon jackets carries the signal, and the interstage coupling is\ndirect. The chassis is die-cast aluminum with an anodized finish, in black here and in\nsilver if you prefer. The volume knob and the power button are machined aluminum too.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThe amplifier chassis measures 6 inches tall, 5.5 wide and 13 deep, and weighs 12\npounds. The power supply matches it at 10 pounds. It runs on global voltage, anywhere from 100\nto 240 volts, so it works wherever you take it without a converter.\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\n\u003cul style=\"margin:0 0 0.9em 0;padding-left:1.4em;line-height:1.6;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou own high-impedance dynamic headphones\u003c\/strong\u003e — the high and low impedance\noutputs cover anything from 8 to 600 ohms, so a 600-ohm Beyerdynamic and a 32-ohm planar both\nget what they need.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou want the WA6 sound with a quieter background\u003c\/strong\u003e — moving the power supply\ninto its own chassis is the single change, and a lower noise floor is what you hear for it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou enjoy tube rolling\u003c\/strong\u003e — the design is self-biasing, so swapping the 13DE7s\nor the 5U4G needs no measurements and no adjustment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo people listen at once\u003c\/strong\u003e — there are two quarter-inch outputs on the front,\none high impedance and one low, and both are live.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYour headphones end in a balanced plug\u003c\/strong\u003e — the WA6-SE fits quarter-inch jacks\nonly, so a balanced-terminated pair needs an adapter, or the fully balanced \u003ca href=\"https:\/\/www.audioadvisor.com\/products\/woo-audio-wa22-balanced-transformer-headphone-amplifier-generation-2-silver\" style=\"color:#8a5a2b;\"\u003eWA22\u003c\/a\u003e\ninstead.\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\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eTwo pairs of gold-plated RCA inputs sit on the back, with a source switch on the front,\nso a DAC and a CD player can both stay plugged in.
