I haven't heard any of the 3 cables indicated but I do have a fair amount of experience with Oyaide plugs, AC and XLR, and their outlets. If you're using stock cords, I can't imagine the Tunami wouldn't be a significant step up. They are quite affordable and come and go often on the audio markets. I say give one a try. If it doesn't suit you, then you could resell for close to what you paid.
Mind the plugs as much as the cords though as the plating can significantly affect the sound. I bought a large quanity of silver plated solid core copper wire years ago and the cords with gold plugs sound rather different to those with silver plugs or palladium plugs or rhodium plugs or platinum plugs...... you get the idea and you can mix and match plugs to achieve the sound you want.
If you don't mind a little DIY work, then I would suggest you buy the wire in bulk and experiment with plugs from Oyaide or Furutech. The IeGO plugs are also pretty good and more affordable except their totl 8095, which is solid silver with a rhodium plate.
