{"type":"firestarter.listing","listing":{"id":"lst_ao_p14r5","product_name":"xDuoo TA-30 Tube Headphone Amp","category":"Headphone Amp (Tube)","description":"\n\nThe xDuoo TA-30 is a tube headphone amplifier that outputs 3000 mW of power and can easily drive most high-end headphones. It comes with several input interfaces, including USB, coaxial, and OPT, while supporting Bluetooth 5.0 decoding as well. Apos Audio found that the DAC chip included in the TA-30 is the ES9038Q2M built by ESS, which also comes with a built-in Time Domain Jitter Eliminator delivering a DNR of up to 129 dB and a THD + N of -120 dB. Finally, the TA-30 includes the 5Z3P and ECC82 tubes that process the audio and produce a sweet refined sound.\n\n\nReview:\n\n\n\"As a DAC/Headphone amp combo, it is among the most powerful units I had the pleasure of testing, it will drive even the heaviest loads I know with an ultimate grip and driver control. It is easily in the top 3 most powerful headphone amps I tested and no matter the music I would listen to, a huge power reserve will always remain on tap.\" - Sandu Vitalie from Soundnews.
