Just like a monolythic opamp, this is why I think smt is the best to use for such a design.
I would have to say it is the most elaborate MM phono yet for me to lay my eyes on!! and I do not know of any other CFA type phono pre-amp either.
Here is one classic RIAA stage using CFA topology from the past. Very easy to build, simple and is not difficult to design pcb. Just a couple of transistors.🙂 You shall be surprised how good it is. If somebody has time to design it, it would be nice to post pcb pdf.

8 Channel APEX A-14 amp build finished, sound awesome. Loud and clear , super silent and perfect of home audio.

Using as 7.1 audio system, with 12inch sealed sub-woofer driven by APEX B500 amp. Getting 7.1 channel analog output via Asus Xonar DX sound card and PC.

Listening to music is a pleasure. And playing GTA-V (PC Game) with surround sound effects is real fun. During game play all channels perfectly creates detailed surrounding audio effects around the player.

Thanks Apex for sharing such a nice amp with us.
