I think some people here have already suggested going to active speakers. These will be your best bang for buck I think. The LS50w are fantastic but you will need a sub either now or later down the road. Elac has a powered speaker now as well that is looking very interesting. Powered speakers tend to go for reasonable prices too in the used market. As you have said you listening to primarily streaming and don't want to be on the upgrade cycle then buy a good set of powered speakers and enjoy. then you don't need expensive cables and the such.
the next option would be an all in one integrated and a set of speakers. with $2k to spend i'd think about $1k for speakers, $700 for integrated and the rest for cables, stands, ect. If you can find something like a newer NAD amp and older pair of ProAc floor standers you'd be doing well and ProAc floor standers don't need sub's.
If your into a more close setting maybe a fullrange speaker like the Omegas. these are very efficient so you don't need much power so saving there in an amp.
Look at Shitt Audio as well for very good affordable audio.
buy used if your can for speakers minimum.
