Ultra-High Performance

A50s uses the same NFCA (Nested Feedback Composite Amplifier) module from flagship A90. Voltage Current hybrid feedback architecture along with? UHGF (Ultra High Gain Feedback) technology provides excellent DC and AC performance. High output current drive capability allows the amp driving low impedance headphones with ease. Ultra-low noise of 0.3uV is miles ahead of the competition, giving an absurdly high dynamic range of 144dB and no audible noise and darkest background for the most sensitive IEMs

6.35mm SE&4.4mm Balanced Output&Aluminum Case.

Although there is only a single-ended input, A50s has a built-in balanced amp circuit. Therefore, it can drive single-ended headphones by 6.35mm output, and drive balanced headphones by 4.4mm balanced output. Moreover, A50s uses full aluminum case with unique workmanship. The outer casing is made of an aluminum brick through CNC precision machining. It is designed with thermal conductive column to dissipate heat from the power supply and OP-AMP through the entire outer casing

2 Step Gain Settings, Adapt to Various Sensitivities

A50s is equipped with two gain settings of 0dB/6dB at SE output(6dB/12dB at balanced output). Wide range of gain settings and the 0.3uVrms ultra-low noise makes A50s easily adapt to all types of headphones from extremely sensitive IEMs to most power demanding full-sized over-ears.

HPA/PRE Automatic Switching

When the A50s is not connected to any headphones, it automatically works in the pre-amplifier mode, and the amplified signal is output from the RCA on the back panel. When the headphone is connected to 6.35mm or 4 .4mm output, A50s automatically switches to the headphone amp mode, and the signal is only output to the 6.35mmand 4.4mm jack.

Wide range of Adaptation to Headphones..

A50s has a high voltage swing of 42Vp-p, power of 3500mW per channel when both channels are driven and output impedance of less than 0. 10hm. It easily drives power-hungry headphones with a wide range of different impedance

Hmm, L30 exists?

Title reveals most of my thoughts, but it is definitely a great device with excellent sound quality. The low noise floor makes it easier to hear the minute details in a recording, but the existence of the L30 makes me wonder. Why would you want this over the L30 except if you're already fully converted to the 4.4mm pentacon connecter. The gain function of this devices is basically useless 6dB is nothing that makes anything difference, and the L30 offers both -9dB and + 9dB. Furthermore you can access the full power of the L30 with single ended. Assumed that the L30 equals this device in sound quality, I can't justify buying this unit over the L30 in less the size difference, or the looks offend you of the L30, this unit feels obsolete and I feel stupid for buying it. Also heard mains hum plugged in with the included power brick on one of my IEMS, but no hiss, so it might go away if you have the P50.
