Hi Nath. I would recommend matching the manufacturer when it comes to plugs and sockets. This way at least you know it's made to fit.
Whilst that may seem obvious you'd be surprised what's inside a lot of basic mains IEC connectors, some of them are real shockers.
One piece of advice I would offer is to get some standard black electrical tape and wrap 2 turns around the IEC plug end, this ensures a tighter fit of the plug into the socket and helps prevent it coming lose. You can also get spring clips mounted to the socket which locks over the input plug which a lot of pro gear uses.
Furutech gets a thumbs up from me. They are a cut above the usual run of the mill connectors. You are getting into bling territory price wise with their rhodium plated offerings but they do not dull off like so many others.
There is such a small contact area in many of these IEC's that they can be spark generators and give rise to noise. Buy right and buy once comes to mind, the cable deserves it and so does your ears.
A gas tight soldered or compression crimp is a better way of getting the electrons into your devices but a whole lot more aggro that most are unwilling to undertake!
Below are some images of IEC connectors. I think they are pretty dire with their small contact areas; it's not until you move up to the 20amp kind that you get better quality and contact areas IMV. All the IP rated connectors are considerably better too, but butt ugly! IEC's are cheap and can be fitted to smaller devices hence their proliferation.
Happy listening.
