    No, not fully discrete - rather a hybrid with opamps for gain and a fully discrete output buffer.

    A fully discrete one? Will you also design the outlook?

    Hi Panson, long time no chat! I'm fine, working on a portable headphone amp design at the moment.

    How are you, Richard? Thanks for your sharing! I have not analyzed the electronic board of A-100.

    They're using TL084 going on what's written in Chinese. Probably you could increase the working impedance to get better SQ from these opamps - that's been my experience with Taobao sourced active speakers.

    The A-100 amplifier does not seem to do baffle-step compensation and HF boost. It does more likely attenuate 5 k to 15 k. At 9 kHz, the attenuation is about 6 dB.
