Minimalized Speaker Length


Wouldn't it make sense to put my power amplifier output terminals as close as possible to the input terminal of my speaker? 

I see all these very expensive speaker cables and how they do this and that, and many discussions about their characteristics. 

In practical theory, why not just eliminate the cable altogether and run say, a 6" cable (or even less) to the speaker?! 

Save all all that money and 'coloring' of the sound?! 

Would not be this be the most ptlractical and 'purist' way to go? 
All the best recording engineers chose the minimum path possible in pro studios. Why not apply this practice with speaker cables? 

I'd enjoy hearing from the AG community on this. Thank you.

+1's for Mitch and cablejockey.
I have recently switched over to Atma-Sphere amps.
Ralph (Atmasphere), recommends using longer interconnects-preferrably balanced, and short speaker cables.
A 6 inch cable is probably a bit too short. You would want a little distance from the amp to the speaker. In setting up the Atma-Sphere Amps, I opted for a 1 meter (3 foot+) speaker cable so I could position the amps away as well as give me some slack to adjust speaker position.
Also, recording studios use balanced cables for reduced signal loss and well as sound 'purity'.
The OP's questions says "my power amplifier". That implies a single-chassis stereo amp, no? To have a short (say 1') speaker cable run, you must either have a pair of mono amps (one behind each speaker), or your speakers only 2' apart!
That is why a lot of people like active speakers

Really? Can you give some examples?
