It is pretty much the same device as PDv2, however, now PowerDAC can work with unbalanced headphones as well. HPToy iOS/Android app was modified to get the switch for 3 output modes:\n\n1) Balanced - the same as PDv2 balanced 2.5mm TRRS up to 600mW/channel output\n\n2) Unbalanced - you can use that mode with E1DA 2.5/3.5mm adapter to drive your unbalanced headphones, however, power in that mode is lower vs Balanced mode\n\n3) Unbalanced Boost - the same as Unbalanced with full 600mW power but with some crossfeed effect. This is the price for the versatility of a single 2.5mm TRRS output\n\nAlso, PDv2.1 got the new USB audio bridge CT7601 Comtrue, instead of Cmedia which was far from ideal.\n\nPDv2.1 has a soft-start function to avoid high inrush current, in fact, PDv2 may work with any Android phone without Y-splitter, if you wish to use such a power-hungry device with your phone.\n\n\n\n\n\nPowerDAC v2\n\nNote: Before you buy this product, please read the FAQ carefully.\n\nNo 2.5/3.5mm jack adaptors allowed! You can kill the DAC.\n\nhttps://e1dashz.wixsite.com/index/faq\n\nIf you have any questions or suggestions, please join us on discord app. The designer Ivan is on line and many users there.\n\nhttps://discord.gg/U9Z28KC\n\n\n\n\n\nPowerDAC v2\n\nYou can call it USB DAC + Headphone amplifier(HPA) &gt;600mW@15ohm but actually, PowerDAC has no HPA at all.\n\nYes, PowerDAC V2 can, as an example, drive LCD3 with 600mW but only as powerful enough DAC, no analog amplification and no feedback are implemented there.\n\nIt's a quite similar to Fully Digital power Amplifiers(FDA) like Sharp SM-SX100(probably earliest FDA), TACT-Millennium, Lingdorf, Wadia etc $5-10K legendary toys.\n\nPowerDAC V2 uses the same or similar Ti digital PWM modulator chip TAS5558 but of course different output stage for headphone.\n\n\n\n\n\n\n\nPowerDAC V2 doesn't need drivers to convert stream PCM up to 24/192 from PC/Mac. iOS, Android or Linux, however, if y","images":["https://cdn.shopify.com/s/files/1/0031/0453/8673/products/e1da-powerdac-v21-headphone-amp-peq-dsp-ble-dac-with-2535-adapter-and-cables-hifigo-484240.jpg?v=1648529958","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/e1da-powerdac-v21-headphone-amp-peq-dsp-ble-dac-with-2535-adapter-and-cables-hifigo-946145.jpg?v=1648529958","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/e1da-powerdac-v21-headphone-amp-peq-dsp-ble-dac-with-2535-adapter-and-cables-hifigo-724094.jpg?v=1621484926","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/e1da-powerdac-v21-headphone-amp-peq-dsp-ble-dac-with-2535-adapter-and-cables-hifigo-386472.jpg?v=1621484894","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/e1da-powerdac-v21-headphone-amp-peq-dsp-ble-dac-with-2535-adapter-and-cables-hifigo-186813.jpg?v=1621484911"],"price":79.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:31.410Z"},"share_url":"https://firestarter.network/l/lst_mXmeWcE2","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
