For now Amazon is a no brainer. If you like what you hear then you could get different cable. It may not sound better just different. You must try in your system to find out.

That's a good idea if you're not sure the ~2W Dave is going to work out or not. If you have a cheap RCA cable you can cut an end off and put the leads in the binding posts of your speakers, just make sure they are wired the same way on both sides. If you can orient the RCA plug's pin to the + binding post even better.
This will give you a way to see if the amp/speaker pairing works out for you as far as producing sufficient SPLs without distortion. If it does a high quality cable will make a significant difference as the Dave is a high performer that likely won't be paired with poor speakers. I'd go so far as to say a Dave/Omega combo won't even approach full potential with a commodity-level cable, so try the Amazon cable or cut up a cheap cable but know it can get much better as far as clarity, tone, etc. Obviously, you won't get more SPLs.

Also, with my Dave cables, they can be converted to a SC that will work well with a tube amp/Omega combo too.
