Audio grade Step down 120-V to 12v DC transformers or Switching 120V/12DC
With more & more AUDIO Eq Mfg coming with Optional AC or 12-V DC operation of their equipment.
The question becomes the noise floor of which offers the best.
One with Linear power supply with a Transformer which creates all sorts EMI fields, etc..
Even though there’s brands like Sbooster from England are very good at this voltage conversion.
But still it becomes its +/- going with transformers baggage. Hum,etc.
Anyone having experience Switching Step down devices not using Transformers vs Electronic Switching?
If so which has found to be a better Performer?? (NOISE reduction.)
did you mean 120vac to 12vdc? I'm going to assume that and then you will not only need a transformer but rectification as well. I think the linear power supplies are still the best but the switching power supplies are catching up quickly. that said Battery/Cap based is better still as long as the battery or Cap system can handle the current demands. something like the below is excellent I've a friend with one in his system and it made a huge difference. https://www.vinnierossi.com/mini/ |
