Adding an extra 1ft to premium speaker cables

Clean power? How about going off grid. Read about Stromtank. If you know the difference between a soldering station and a train station, get your soldering iron out and build yourself this type of device. Don’t be an armchair audiophile.

Thanks for the assistance everyone. So here's the real moral of the story. How could any high quality speaker cable at any price maintain its integrity unless it were connected directly to the internal crossover or source? Almost every speaker is going to have an additional foot of internal cable or wire connecting the crossover to the internal speaker terminals that the end-user doesn't see.

My Raidho td1.2 uses Nordost cables for all of their internal wiring. You made the assumption that the internal cable is the weak link. That’s not necessarily true. Some manufacturers pay a lot of attention to the crossover components and wiring.  It’s kind of unfair to put everyone in the same basket. 

@rankaudio Interesting perspective.
 

There are numerous audio companies recommending use of high quality cables and a market that has existed for decades.  I’m not sure if you’re philosophical question will impact the experience and decision of others.

spenav and overthemoon, I agree with you both. No doubt there are speakers with good internal wiring. Could be the opposite situation in some cases like you’re indicating. I’m just merely pointing out whether or not the cables can remain faithful for either case if there’s two different cables. Thank you for sharing.
