I think set up and cables would be the route I would make sure are up to snuff.
You do not say what cables you are using but I have always thought wire was one of the cheapest ways to improve performance - in particular a Gabriel Gold Revelation MKI interconnect for about $300+ would give you a lot of detail (it trounced some pricey wire in my all tube system) and a good standard speaker wire is Alpha Core Goertz Veracity MI2 - very clean and clear with terrific tone.
The Rogue gear is pretty detailed and clear, not up with the best out there but pretty darn good so look elsewhere IMO.
