As someone who went battery power 4 years ago (my, how time flies) I can testify to the drop in noise and distortion compared to house AC power. Even though I’m using a Lithium battery powered Sony Walkman CD player with SONY MDR-v700 headphones, a modest set up, I’m sure you will agree. In fact my set up probably wins the low mass award and the low cost award. No more AC noise, AC ground issues, no more power cords, no more speaker cables, no more interconnects, no more digital cable, no more transformers, no more big honking capacitors, no more fuses. You know, all the things that produce noise and distortion. Hel-loo! No more pencils, no more books, no more teacher’s dirty looks. 🧐
Going Battery Powered
I have a number of components that run off of 12V DC power. This includes my DAC, preamp, tube buffer, etc. I’m looking into powering them with batteries instead of 120V AC power supplies. Does anyone have any input on if this is worth my time? Seems like DC power is the cleanest power you can get in this situation. I’ve heard batteries can have reduced dynamics but I plan on using as big of a battery as is reasonable, most likely a large sealed AGM type battery. Do I need power supplies/voltage regulators if I use a large battery and only power low draw components (no power amps); e.g. the max amp draw is probably around 1-2 amps, if that. If I do, does anyone have a link to a design for the power supply/voltage regulator? Thank you.
