There is a company that sells higher output power supplies for NAD phono preamps. For example the PP1 comes with a 15 volt/100ma power supply. They sell a 15 volt/600ma version as a upgrade.
For the PP2 they supply it with a 24 volt/400ma version instead of the stock 100ma version. as a further upgrade they have a 1000ma version.
I don't have a real understanding of electronics but I question whether this is safe. I was thinking of ordering the 600ma version for my NAD PP1 but I'm also interested in upgrading my Project Phono Box SE. It comes with a 16volt/500ma stock, I'd like to get a 16volt/1000ma version.
The fellow that sells them for the NAD units claims the higher output units improve the whole audio spectrum, wider and deeper soundstage, more powerfull bass, better dynamics and timbre.
Can someone tell me what is happening here. Will increasing the ma output harm the preamp in anyway?
