Adding an extra 1ft to premium speaker cables

FYI. My dealer dropped by a Nordost Odin 2 set of interconnects ($20K). After a couple days I had to take them off because they sounded so good... I was starting to think about how I could put together the money to buy them... they were strung between $20K each components. I kept them much longer and I was going to figure out a way to do it. They were connected with traditional RCA connectors. 

I am certain the story would have been the same with their speaker cables... only they would have been much more expensive and the difference more pronounced. 

I did a comparison in the 1990’s and included a Home Depot 12 gauge power cord (with ends cut off, cut to length), cheap Radio Shack speaker wire and a set of Transparent and Cardas Speaker cables. The Home Depot sounded great... it was better than the Radio Shack stufff... I might have compared Monster (I know I compared several Monster products... they were no better than the what comes with components, speaker wire may have been one of them). The Transparent and Cardas were much better... and very different from each other. At the time I think I had a Threshold preamp and amp. I have much better equipment now. 

I will say, that my office system is still using a Home Depot power cord speaker wire. If you don’t want to spend more than $100 - $150... it is a very good alternative. I find the lower tier speaker wire, power cords and interconnects, generally of little benefit... especially the  hooking up budget components. I have a Schiit Gungnir multi-bit DAC, and Prima Luna Integrated amp, with Totem speakers on my office system. I am sure if this was my main system... I would research the heck out of it and find some used $1k cables and interconnects that would improve the sound a little.

A common dilemma. 

I have gotten stuck in this situation before. I am an audiophile, so the answer was easy, be financially irresponsible, and buy a new set of the correct length. Hence I have no experience. 

However, given my experience with cables, I have a guess. With lots of caveats. Adding an extra foot of less expensive (note I did not say cheap) would sound better, than say just a full run of low quality cable. I would put the less expensive stuff attached to the amp. Hopefully it is like one tier down of the same brand of cable... not a completely different brand of cable... or hanger wire or something, 

There are so many problems with my rational, they are hard to count. That’s my guess.
