Author's Professional Amplifier 16-600 Ohms 20Hz-20KHz class A

  We offer author's headphone amplifiers that can be connected to the DAC output, computer motherboard, media player, smartphone, and other analog signal sources.

  In terms of technical parameters, it surpasses more expensive and famous models.
The amplifier is universal, suitable for headphones from 16 to 600 Ohms. For a low-impedance load, it has a current margin, for a high-impedance voltage. It guarantees a loudness level of 115-120dB even for iso-ortho-dynamic headphones with low sensitivity.
It allows you to hear all the nuances of musical material, volume, localization, width, depth of the stage.

  The very low output impedance of the amplifier ensures neutral sound without distorting the frequency response of any type of headphone or impedance.
Noise and hum are completely absent at the maximum position of the volume control and open input.
A high-impedance load> 50 Ohm provides Class A operation.
Reliable protections will ensure the safety of your headphones.

  Amplifiers already work with headphones of different types and impedances from 8 to 1000 Ohms, including AKG K240 Sextett, AKG K340 ED, AKG K401, AKG K612PRO, AKG K701, AKG K702, Audeze LCD-XС, Audeze Sine, Audio-Technica ATH -ES7, Audio-Technica ATH-M50X, Audio-Technica ATH-W5000, Beyerdynamic DT 770 Pro, Beyerdynamic DT 990 Pro, Beyerdynamic T 70, Bosch LBB 9095/30, Fostex T50RP MK3, German Maestro GMP 450 pro, HiFiman HE400, HiFiman HE500, iBasso SR1, Monoprice Monolith M570, Monoprice Monolith M1060, MrSpeakers AEON Flow Closed, Philips SHP9500, Realistic Pro 30, Sash Deux, Sennheiser HD206, Sennheiser HD380pro, Sennheiser HD599, Sennheiser Sony HDpro650, Sennheiser Sony HDpro6 MDR-CD3000, Sony MDR-Z7, Superlux HD660, Ultrasone HFI 2400, Yamaha HPH-MT5, TDS-5, TDS-7, TDS-15, TDS-16, ECHO-N16-40 and, according to the owners, have shown themselves with excellent side.

The amplifiers are available in 2 versions:
  • Option 1 - with a pre-amplifier function. Line-out with amplification and volume control. Can be used with power amplifiers, powered monitors, etc. Disables when power is removed.
  • Option 2 - the line output duplicates the input and is not regulated. Convenient to use in a system with an independent headphone connection. When the power is turned off, the signal at the line output does not disappear.

Warranty - 24 months
