I'll agree with your dealer with the suggestion of the Hegel H300. The Hegel will drive any of those speakers easily. You can get yourself an Oppo BDP-103D as a source and run the s/pdif coaxial digital out to one of the coaxial digital inputs of the Hegel H300 and use its internal DAC. The DAC quality in the H300 is very good. Then, you can connect your Oppo to your router via Ethernet cable (preferred) or wifi and use the Oppo as a digital media renderer. So, you can push music to the Oppo using various media software. If you're using a PC, I'd recommend not using iTunes and going with JRiver Media. There are a couple of great apps that can be used to control JRiver Media (JRemote on ios or Gizmo on Android). On the MAC side, there are a number of options definitely better than iTunes as well. This would make an excellent and very simple system for what you're doing. The Oppo works very well in this capacity. The only downside is that it doesn't support gapless playback as a digital media renderer like this.
Disclosure: I am a dealer for Hegel and Oppo. However, I'm just confirming that his local dealer presented him a good option.
