Should I update my manufactures power cords?

And you as well @bigkidz

I conducted a survey a few months ago to formulate a group consensus related to the subject of premium power cords.

Here’s a link that provides the specific survey questions, a brief conversation between contributors, as well as a link to the results. This should provide some indication of the group’s adoption of this product category.

+1 On For better performance on amps take a look at Zavfino

I appreciate everyones comments and the survey results. How do you distinguish between PC for use with each piece of equipment, for example, MC611 amps or hifi rose 150b?

The amplifier power cords are going to have more impact than the cord on the streamer in my experience. Do the power cord upgrade on the streamer last.
I would suggest getting the best possible power cables you can afford for the amps even if it means using stock cords on the streamer and preamp. Second upgrade would be the preamp power cord. The very last thing you’ll want to do, as icing on the cake, is to upgrade your Ethernet cable. If you’re using basic cheap Ethernet cable, an excellent makeshift improvement would be something like a Linkup cable from amazon.
