With its double tube amplification, adjustable bass and treble, and compatibility with a range of audio devices, it delivers a warm, dynamic sound that's designed to complement your LP records' unique charms. \nAmplifying Signals\nThe output level of turntables is usually very small, about 3mV. That's where this unit comes in, amplifying the signal dozens of times over to allow your music to reach the power amplifier in a high-fidelity form.\nCompensation Frequency\nThanks to the compensation frequency, this device helps mitigate any attenuation of low and high frequencies that can occur during LP production. This feature ensures your music remains smooth and balanced, regardless of how long your record has been in use.\nTube Phono Amplifier\nThe MP-01 Tube Phono Preamp uses two 6N3 tubes for front-stage amplification, delivering a soft and delicate sound. Plus, the design allows for direct tube replacement with models like the 6H3N or JAN-5670W, letting you explore different sound styles.\nBass and Treble Compensation\nWith independent adjusting knobs for bass and treble, you can easily bring back any lost high or low frequencies from the recording head, allowing for a more comprehensive listening experience.\nHeadphone Output\nWho says you can't use headphones with an LP player? The MP-01 Tube Phono Preamp features a headphone output so you can enjoy the unique charms of your turntable with your favorite pair of headphones. \nCompatibility\nThis preamp doesn't just have a PHONO input; it also boasts an AUX input. Compatible with MM/MC phonographs, computers, mobile phones, CD players, TVs, DAC decoders, MP3 players, and more, the MP-01 is ready to meet the diverse needs of modern music lovers.\nQuality Capacitances\nBuilt with Japanese Rubycon and ELNA capacitances for the main filter and coupling capacitance","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022833434860.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022833041644.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022833008876.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022832681196.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022832976108.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022832779500.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022832713964.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022832746732.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022833074412.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022832943340.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022832812268.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022832615660.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022832910572.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022832877804.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022832845036.jpg?v=1774351717","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-amp-tube-xduoo-mp-01-tube-phono-preamp-headphone-amplifier-39022832648428.jpg?v=1774351717"],"price":149,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:59.421Z"},"share_url":"https://firestarter.network/l/lst_9XzxF1Bn","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
