Feliks Audio amps

A quick search on here suggests that a surprising number of posters own or owned variants of Feliks Audio headphone amps. I’ve multiple questions.

1 - any of you still around?
2 - have you stuck with Feliks?
3- how would you describe the sound?
4 - how did you get to hear before purchase (if you did)?
5 - any experience of their two products which power speakers?
6 - anything else I should know?

No-one?

@Steffen? @der_luda?

Gotta be some still left here surely?

A-Fin? robpearson? DougieDanger? Sten?

Additional question?

What are the input impedances on your amps? Looking to fire my Churd DAC in PRE mode which outputs a fixed 3V.
