Karel,
I am so sorry to hear of your immense loss. I cannot imagine what you must be feeling right now.
With respect to your question, realize that it may not be the best time to consider the future of your audio system, especially if it turns out to be a powerful way to continue sharing the music with your wife. Just take care of yourself, and when the time is right, listening to your system could be exactly what soothes you most.
