About this item
- 6.35mm SE & 4.4mm balanced output ---Although there is only a single-ended input, A50s has a bilt-in balanced amp circuit. Therefore, it can drive single-ended head- phones by 6.35mm output, and drive balanced headphones by 4.4mm balanced output.
- 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. 1Ohm. It easily drives power-hungry headphones with a wide range of different impedance.
- 2 step gain settings, adapt to various sensitivities ---A50s is equipped with two gain settings of 0dB/6dB at SE out- put(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.
- P50 could provide cleaner power to A50s ---(When powered by P50, max balanced output power of A50s drop to 2 4W x 2, other power spec is not affected)
- HPA/PRE automatic switching--- When the A50s is not connected to any headphones, it automati- cally works in the preaplifier 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 6.35mm and 4.4mm jack.

Reviewed in France on March 25, 2023
更に音質向上をと、ヘッドホンアンプを追加購入しました。
環境は、
foobar2000(Win10)
UA3-R010(エイム電子)
AL-38432DR(Amulech)
Clear force Ultimate(ORB)
ATH-CKR100(audio-technica)
です。
先月UA3-R010のエージングがほぼ完了して音の基準が出来たので、
そこに本製品を追加しました。
ただRCAケーブルは未購入で、とりあえずAV機器にオマケの赤白端子のものを繋いでいます。
初日の印象としては、本製品が無かった状態と比べて、ドラムやベースの押し出しが強くなり、落ち着いて聴く感じではなくなりましたが、ベースの弦の震えが今までより見えるようになり、弾けるような元気さも増しました。
ヴォーカルは少し前に出てきて声のザラつきが明瞭になり、呼吸もよく聴こえるようになりました。
上原ひろみさんのアルバムだと、今までよりも沢山の彼女のヴォーカルが聴こえるようになりました。
抑揚がよく分かるようになり、実は細かいところで抑揚付けていたんだな、というのが分かるようになりました。
コーラスも力強く明瞭で主張があります。
ギターの中低音が強くなり音が太く感じられます。
シンバルやハイハットなどは、もしかしたら今までより主張が減った気がします。
全体的に元気な印象ですが、今までより音の分離が良いのでゴチャゴチャしてるようには感じませんが、
曲によってはしっとりした感じは損なわれた気がします。
RCAケーブルは「BELDEN 88760」を購入予定で、届いたら改めてレビューの予定です。
