Going Battery Powered
jzzmusicianJust another BS voodoo snake oil product like ($1) $150! ac mains fuses, but this ones a $300! contact cleaner https://perfectpathtechnologies.com/product/total-contact/ Electronic engineers use as good if not better one for $22, but it's not got an "audio" snake oil signature to it. https://www.ebay.com.au/itm/DeoxIT-Mini-Gold-spray-GN5MS-15-14g/401602406187?epid=6024006287&hash=item5d815e672b:g:954AAOSwgHpa28-g&frcectupt=true Cheers George |

Just to mention there is no power or dynamics issue with low-powered portable CD players. That’s actually one really big advantage of low mass systems, the ability of teeny tiny AA or AAA Lithium batteries to provide full dynamic range without constricting dynamics. You just can’t use certain headphones like some Sennheisers. I use a vintage SONY MDR-v700 and Grados and others, no problemo. |
The areas where DC power gives you the best return is where the signals being amplified are tiny such as in a phono preamp or turntable. I have an turntable that is battery operated and a Nagra phono preamp that runs off a 9 volt battery. Unlike others, I cannot say there is a big difference sonically in the phono pre with the battery Vs the wall wart, but with the turntable where I am using a low output moving coil the noise floor and degree of hum are much improved. I would not bother going to the expense of using a battery/inverter with the downstream electronics contrary to what others have said. If you think you are dealing with dirty or fluxuating AC try a good power conditioner first. The other part of this equation is how sensitive your speakers are. If you have 100 db efficient speakers (as I do), getting as much hum out of the system as possible by isolating and grounding your speaker and interconnect cables will give you a bigger return than going off grid (IMHO). Good Luck! |
Don't stoo at the 12V parts, get a battery that handles it all ;-) http://www.enjoythemusic.com/superioraudio/equipment/0218/Stromtank_S2500_Battery_Power_Review.htm It is probably good but it costs a lot. |
