I just got Hyrlo and Ferry.
They sound great and seem to be built like tanks.
The ability to send modular audio out to my iPad through an audio interface and bring it back in stereo AND for that stereo input to be routed with jumper wires on the back as a fourth input to Hyrlo is brilliant!
My only possible issue is that the knobs on Hyrlo are pretty tightly spaced so you’re not going to be very performative with them unless you have small hands…
I’m considering replacing them with smaller diameter knobs but am still trying to decide.
