Banana Plug Wall Plate w/Cabling

After recently talking my wife into accepting some small floor standing speakers (GoldenEar Triton 7s). The tradeoff is that I have to hide cords and components -- except the turntable. That's ok to have out w/vinyl collection.

So this is what I am planning:

* Run some Belkin wire from BlueJeans directly from the Peachtree Nova 125SE inside of a cabinet, down through the floor, and up into the wall near the speakers.
* Terminate the wire at a banana plug wall plate for each speaker.
* Run a short 1-2 ft banana plug speaker cable from wall to speaker.
* In addition, I have on order the Xantech IR receiver that would be wired to control the Peachtree located in a cabinet along with Rega Fono amp and Apple TV.

So here are my questions:

1) I suspect many on this forum would advise against having a wall plate connection between my amp and speakers. Maybe this is heretical in these parts;) So what are the problems of doing it this way, and is there a better brand/maker for these types of wall plates? The ones at BlueJeans are out of stock.

2) The cable runs to the speakers are of unequal length (20 vs. 10 ft). I am assuming I should run the lengths of wire the same even though one will be much longer -- or is this not necessary?

3). Assuming the amp to wall plate is OK. Does the last stretch of 1-2 ft. cable from the wall plate to the speaker matter in terms of type of cable? Just continue the Belkin?

As for placing the amp in between the speakers, this is not an option with the room layout. Also, I know there are wall plates that just allow cords to 'exit' and keep a single run, and that might be an option, but I know my kids would probably pull on them and push legos into the holes.

Just wondering your thoughts/experiences.
