{"type":"firestarter.listing","listing":{"id":"lst_BtFb0kO6","product_name":"Apos x ES Lab Integrated Amplifier","category":"Headphone Amp","description":"Note: The product in photo is a prototype and subject to change. Interested in being updated about this launch? Enter your email in the field above. \nComing soon...\nMost systems force you to choose a lane: the high voltage and specialized outputs of e-stats or the high wattage of passive speakers. But not this design. This one unit can power your e-stats, your planars, your dynamics, and your speakers, all without adapters, workarounds, or stacking multiple amps on your desk. \nIt's a pre-amp, a head amp, an e-stat amp, and a power amp rolled into one. \nDon't get hung up on the amateurish-looking taped-on labels and daughterboard. This is only a prototype! If you want to stay in the loop as the design evolves and we approach the launch date, throw your email in the form above. \nProduct highlights\n\nClass A/B topology\n
