Respectfully if you are able to have your Devialet that close to a wireless router, I don't think purchasing a new router will make much of a different. I wonder if you are getting interference from other wireless networks (neighbors) nearby? This article provides some guidance on how to determine best channel to set your router.

I had an Airport Extreme and it worked fine, I do now have an ASUS RT-1900 and that works great too. Bear in mind this was with a Devialet 200 than 440 than 440 Pro, so it has slightly more sophisticated capabilities, including support for ethernet and better wireless support.
I wish I had better answers for you, I know it must be super frustrating.
