Speaker cable + jumper cable for RTi A7s

adrift02

Background: So I've had my RTi A7s for a couple months now (powered by a Denon x3300) and am finally moving to upgrade the rest of my setup accordingly. I now have a B&K EX-442 amp on the way (thanks all for the feedback on that forum post) and want to upgrade my cables too (currently using some random Frys cable with random bananas I bought a while back).

First, I picked up some BJC LC-1 to run between the receiver and amp after reading the forums for recommendations. $36 for a 3 foot run, ok: https://www.amazon.com/gp/product/B00OJLNEOU/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

Second, I read the forums looking for budget speaker cable (something cheaper for longer runs) and saw the Canare 4S11 recommended a few times. Ended up ordering this for ~$88 (two 10ft runs): https://www.amazon.com/gp/product/B00SPVJDRW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

**FIRST QUESTION**
I didn't realize there may be a difference between companies putting this stuff together. Should I have ordered BJC 4S11 (https://www.amazon.com/Blue-Jeans-Cable-Conventional-Terminations/dp/B01N1NZDU6/ref=sr_1_fkmr0_3?s=musical-instruments&ie=UTF8&qid=1492198933&sr=1-3-fkmr0&keywords=Canare+4S11+Star+Quad+14+Gauge+Cable+bjc) or am I ok with what I bought? Looks like I can get the BJC 4S11 for about the same price if I jump down to a 6ft run, which should be ok (the 10ft buy was for future-proofing).

**SECOND QUESTION**
I'd also like to replace the stock jumper plates based on recommendations here. I saw an image of ones that go from a banana to spade, which looks ideal. What would be a good pairing with my current purchases? I like a warmer sound, but am pretty sure the EX-422 will offset anything the cable will do to the signature. Mainly just looking to pair accordingly.

Thanks for the recommendations.
