Speaker cable recommendations

Hello! I'm currently looking for some speaker cable recommendations. Current system is Luxman L509x to ATC SCM20s and I've been using Belden 9497 to connect the two. I have roughly 10 ft between the left speaker and amp which makes for a more expensive cable.

I've been wanting to stay around $300 or less but the options that have been recommended to me tend to be above that.

Options that I've been considering - 

1. Wireworld Solstice - there's a sale right now and I can get biwired for $250
2. DIY Duelund 16GA for tweeter/12GA for bass - for the length, I'm looking at ~ $550 biwired from partsconnexion
3. DIY Neotech NES-3004 MKII - ~$600 
4. Used Analysis plus - it looks like I can only afford Oval 12 around this price range. 

Any suggestions on which direction would go well with my system? I've been leaning more toward the Neotech since I've read the duelund has a specific sound that it goes for and Neotech should be more neutral. I have no experience with any of the cables above so any help would be appreciated.

Thanks!
