Could you share how to get it ? any schematic ?

WRT to the battery bias I am not sure it sounds any better than a very well filtered bias supply, but it is one of those silly things that amuses me these days so I do it. (See my Muscovite phono thread in analog source for how many batteries and chokes you can put in a phono stage. )
Do you take a battery for gird bias in the 1st stage ? whith this, you can ignore a Ck (a bad Cka must worsen sound quality much).... so sound is maybe improved . For me, the lesser electric capacitor in the line of audio signal is the better.

I take lowering gain and increasing current for 1st stage, sound become stronger, more dynamic but less sweet a bit
