Headphone amp for retro gaming consoles

[Marin]

I have Focal Elear and I would like to use it with retro consoles (PS1, N64, SNES, Mega Drive), they don't have digital out, and built in dacs aren't that great.
I'm looking for reasonably priced amp that will do the job.
The only other hardware in my retro setup is Sony PVM 20M2E reference RGB/YPbPr monitor;
And don't worry I have proper Hi-Fi setup for music, this is just for "retro corner" of my home.

The Fiio A3 is a very good little headphone amp for the price. It's portable, but you can leave it plugged in.

I'm sure that it's good enough for my setup, but it would look so out of place, and I don't like 3.5mm jacks, I would much rather choose something with proper rca and 6.35 mm jack.
Also I'm good with soldering iron if someone wants to suggest good DIY kit.

Maybe something here? http://hifimediy.com/amplifiers/diy-amplifiers. I have no idea if they meet your jack requirements.
