Sorry, I was not talking about the power cord to the unit.....but the AC receptacle, switch, fuse, and wiring to the power supply board INSIDE the amp:....Eliminated the switch (already has a switch on the front panel), eliminated the fuse (already has a fuse on the power supply board (which I have not upgraded....YET), and changed the inlet to Furutech and upgraded the input wire and hardwired it to the power supply board (no connector). I did this exact mod to the LSA Voyager GaN amp and it made it a little better....but this was mind blowing. Probably because the stock parts were so bad and the fact that the signal path is so short (no DAC, no preamp, no analog cables).....so whatever you do to this ONE thang....it makes a serious improvement. I should have most mods done by this weekend and will post all info on my website.
For external power I am using a Goal Zero Inverter and my own hand made power cord. You HAVE to GET OFF the Grid. Please read my thing on my website about using the Giandel 5000 watt inverter, etc. (When I get the money, I am getting a Giandel....it is worlds better than the Goal Zero thing I have). Yes, the Puritan line filter improves it more....and modding the Puritan takes it further (just now getting in the Furutech NCF jacks to mod another Puritan).
