As with many electrical components there are sooo many interactions between components…resistance, inductance, admittance, reactance etc…et all.
Look at the rats nest wiring of vintage and even some new tube amps…its a mess…but it works “somehow”. With differing levels of distortion, crosstalk, and the electrial interactions like the transformer.
Schiit just announced the Loki Maximus EQ…and states due to the proximity of it to other devices you can pick up “hum”…
Possible yes…But always a but…how do you attach, will one transformer work with all devices, what is the affect on the amp? Does it add or take away stuff that might affect the output or sound?
