I mentioned the Neotech because it's something I would like to try.
You might also look into VHAudio bulk wire offerings (wondering if their much less expensive interconnect cable would work well as short speaker cable)?
Hoping that you will experiment with the better version of the Neotech 22 gauge solid core copper, just to hear your feedback.
Single runs of smaller gauge solid core copper speaker cable can (most likely will) offer somewhat less tight bass, which I prefer, but not reduced bass as many suspect/think/believe (quite the opposite form my experience).
Years ago when I ran 12' runs of the tiny OTA between an Audio Silver Night DH/SET 300B amp and Reynaud Twins MkII two members "here" who listened to the setup asked if I had a sub hidden under the bentwood settee located between the speakers.
The Audion was SS rectified and I suspect that the small gauge OTA reduced the damping factor to some degree with the 12' runs.
One thought he busted me (he stayed the weekend) when he found a wooden box tucked way back under the settee, but it was a wooden crate containing a 3 liter bottle of Italian wine that I was storing for an upcoming patio party.
