Default Passive Pre with UCD180ADs


I've been using the DIY Paradise Maggie passive (autoformer) preamp with my dual mono Hypex amp for about six months.

Very good, no problems, didn't even check the impedances matched (forgot it might be an issue). Prior to this I had bashed together an Alps Blue pot based passive - worked fine but no comparison to the transformer approach.
