Cables are like tone controls or another equalization method. Depending on how the system sounds currently and what direction you want it to go in, that is the thing that should influence your decision.
You could get very neutral cables, but that might not help out the overall sound if there is a sonic mismatch between components. Synergy is key. But now you must also be realizing that asking for a cable suggestion on a forum would give you ALL sorts of answers when the only real answer can be had by you alone depending on what YOU hear.
The short of it is that you will have to audition different cables and decide accordingly in your system.
Finally, I would strongly suggest you stay with extremely high purity copper, preferably OCC copper which is extremely high purity and each crystal is extremely long with less barriers to the electron flow within the wire. Preferably cryogenically treated to assist further in signal flow.
There are many OCC based wires depending on your budget.
I love Furutech cabling and will suggest you try that. There is also Jena wire that I really liked as well.
By the way, I absolutely HATED Nordost Valhalla cables as they are too edgy and can easily throw off a well balanced system. That cable can be used to wake up an slow and boring system easily!
