Single ended speaker cables or Shot gun config?

As mentioned above, it probably depends on how your speakers are designed so you might wanna talk to them and get their take. My experience was that shotgun bi-wire provided marginal improvements not commensurate with the cost over single wire with good jumpers. I’d make sure everything else was squared away including things like power conditioning, room treatments, etc. before considering going shotgun bi-wire because they’re probably more consequential. Hope this helps at least somewhat.

Both my TAD and Vandy are biwired and sound better for it. Be sure to separate the shotgun by > 2” … An internal biwire without the magic separation is one cause for the lack of appreciation…. imo

Spring project for me will be modified Apogee for biwire…

But listening and checking w manufacturer of the speaker is excellent advice 

I would get the matching jumpers from the same cable manufacturer or make my own. I doubt you will hear the difference with a shotgun cable since one pair of binding posts will still require jumpers. Connect the way the speaker manufacturer recommends and you should be set to go. Don’t overthink it. You’ll probably spend more on a shotgun cable and depending on speakers and the rest of your system gain very little if anything at all. 

The bsss is not as critical o the ear  as the mids and highs use like a Kimber 8 or 12 TC or a Wireworld equanox for bass both are Litz cables the wire world a bit better.  and the better for the top mids and highs .

@audioman58 the bass is absolutely critical. It’s what balances out the entire presentation. Lack of bass is what causes brightness. Too much bass and you lose details. Bass also helps to create harmony in music. To think bass is not critical is a gigantic mistake.
