CTOnews.com December 16 news, iBasso Albaso new ear amplifier AMP14 new product on the market today, the price is 1888 yuan, using Nutube vacuum tube, 4.4mm balanced ear amplifier card. DX320 / DX300 users enjoy a 35% discount based on the SN code.

AMP14 adopts the sixth generation Nutube 6P1 three-pole vacuum tube jointly produced by Korg and Noritake in Japan, which has the same warm and charming timbre as the traditional vacuum tube. Compared with traditional electronic tubes, Nutube 6P1 has a service life of more than 30000 hours, only 30% of the volume of traditional electronic tubes, and lower power consumption, which meets the needs of portable equipment.

The voltage of AMP14 is amplified by Nutube tube, which has strong gallbladder taste and mellow sense of hearing. JFET load sharing technology is integrated to achieve balanced output of L -, L +, R + and R-four channels. CTOnews.com learned that for better sound effects, AMP14 uses two JRC volume control chips, which are responsible for four-way volume balance adjustment, and finally drive headphones via four-way buffers. Choose the industry benchmark Pentaconn original factory 4.4mm balance mother seat, excellent acoustic effect, durable.

The AMP14 tube adopts cathode input, which reduces the cathode impedance and reduces external interference. AMP14 has excellent bottom noise control, pure sound, full and powerful low frequency, which can bring a better streaming listening experience.

The digital part and ear amplifier of DX320 / DX300 have their own independent batteries, which provides a reliable stage for AMP14, which is a more power-demanding ear amplifier card. AMP14 uses two Lint high-performance power chips, a total of 4 DC-DC, one for 3.6V for cathode and one for 14V for anode. In addition, + 8V and 8V constitute the 16V voltage swing needed to feed each operational amplifier.

All AMP14 are tested by AP audio analyzer, with 3 imported multi-circle precision potentiometers, which are calibrated and matched by engineers by hand, showing the best parameter performance of Nutube. With DX320/ DX300, we can not only realize the pure sense of looseness, sweetness and moisturization of bile duct, but also have a simulated atmosphere of quiet and deep, harmonic agitation.

Before using AMP14 compatible DX320 / DX300, please update the player to the current version of firmware to get better support for AMP14. When listening to streaming music, AMP14 may experience subtle WiFi interference noise during data buffering. It's almost inaudible at normal volume. If the sensitivity and impedance of headphones are different, the influence may be different.
