Yes the room treatments and set up are also key, sorry I left that out (stupid me)but in the end the speakers will limit the system sound to whatever they are capable of. The system sould change significantly with Vandy 5As versus all the treatments that I know of. Depth in my system became more real when I used a speaker that was capable of adding lower bass and extened highs. Treatments are a key system concern too.
Happy Listening.
