Surely not! What's the virtual piano you're using? Sounds incredible.
One of my first 'spensive VSTi purchases a few years back: Pianoteq (using the upright piano addon I bought a few months ago). The thing first made its cubus debut with Für Alali but with every new version the realism just gets better and better.
What's even more remarkable is there's no samples used whatsoever in the plugin, it's all physical modelling! The installer is only like 25mb
