Here's my completed project. The walnut y-splitter wasn't meant to be, so I purchased and metal one and that took a while to receive; wasn't going to pay more for shipping than the price of the item, which is what took so long (thanks to delayed shipping and UPS Ground). The 12 conductor wire isn't too bad in weight due to the 6ft length, but if I had to do it again, I would stick with 8 conductors and call it good.
For sound, I'm still trying to find the time for a good listening session and compare it to my RS2, which probably won't be for another week.
Are you going to write a review for those?
