SYNERGESTIC RESEARCH - GALILEO SX INTERCONNECT- XLR

At this price point. You should ask for at home audition and you can figure out which one sounds better to your ears. Your dealer will be more than happy to help you.

Your ICs are great and I am not sure that the SX is going to bring much more of what you are seeking. Top power cables have the effect you are looking for. What power cables are you using?

What components are you connecting with the IC. Maybe someone can tell you more when you provide more detail at least in general.

Yes. Check the other forum as well. 

In my opinion the power cables have more impact on sound than interconnects. Gigawatt is not known in the US but their conditioner seems very good. I bet that cables like Shunyata Omega or Synergistic Research SRX or Nordost Odin 2 or the expensive offering from Ansuz  or my moneoone Supernova will be much  better than LS-2 from wall to your conditioner. It will likely be a cheaper upgrade with more impact than the IC.

Yes. These cables are expensive and I thought you are going after used market. 10k USD cable can be purchased at half price used. Gigawatt LS-2 is 3.6k EUR new. Not much of a difference in price then but huge performance difference.
