To be frank, its been quite a while since I hear the name Ryuzoh pop back up.
The only time I heard of him was through a headfonia review that talked about modding a Mojo to have a balanced output.
And apparently, guy's a wizard (not sure to what degree) and can make just about anything sound wonderful.
I am a bit scared to know how much he can do to a Fiio X1 with its modding potential due to such low cost.
What's great about Ryuzoh's mods are they're usually cost-proportionate to the actual device itself, i.e. his AK70 mod isn't as costly as his AK240 mod, which isn't as costly as his AK380 mod, etc. So, you might be in luck with a decently budget Fiio X1 mod on the table
Wow, is your dad an audiophile too? How i wish i have some siblings or friends who share the same interest as me
He's not as crazy as we are here, but a lot of my friends/family are musicians/audio-literate, so it's certainly a very familiar circle
