A 15 foot pair of Rocket 44 Premium No Frills at audio advisor is $515. The premium version uses better Pangea spades/bananas than the regular no frills:

Or you could move up to Rocket 88 no frills for $1049. It uses better copper and would have better resolution, but doesn't have the Pangea banana/spades:

I would NOT bi-wire these because it splits apart the conductors and you end up with smaller amount of overall bass/mid conductor. Just get a normal pair and connect it to the upper binding posts on the Electa. Then use a really good jumper to connect upper/lower binding posts.
However, if you wanted much better resolution, I would get the rocket 44/88 and chop the ends and re-terminate with Furutech Rhodium FP-201 R spades available for $17 each from Sonic Craft or Parts Connexion. The gold-plated terminations are nice but warmer in sound and don't have as much high frequency resolution. You could start out with the gold and then chop/upgrade to rhodium later if you felt you needed more resolution. The rhodium will also have tighter deep bass as well.
