Hope you get the appropriate support from your human surrounding. It's a challenging situation anyway. Do you really bother with a textbook stereo impression? Maybe it is time to re-evaluate the merits of such an approach. Look, I myself never listened to a real stereo for years. I have it all, top-notch linearity, absence of distortion, best directivity, narrow or wide with big or small speakers, good amplification, 24bit sources, but sitting at least 30° off-center. I actually cannot stand the irritation that a conventional stereo presents - I rather drop it.
The LS50s are a bit small for most use cases. A sub won't help in too many situations either. Get something like the R3s with a bit of e/q if not meta approved, and I really hope it'll make your day. All the enjoyment is in the imagination. Some device will support it more, but, It is all up to the personal involvement.
