Just spotted this thread for the first time.
This is my current dungeon workout setup: SMSL-AD18 bluetooth amplifier wired to a pair of Klipsch RP160M's and using my Shanling M1 player with all of my CD's ripped onto it in FLAC. I will also use my phone streaming 320kbps and that sounds pretty good also.
Can't say enough about the Klipsch's...they punch well above their size. They are really efficient (96db sensitivity); the little amp has no problems driving them to clean ear bleeding levels. You would swear I have a small subwoofer hiding but I don't...they are impressive speakers for their size. If your in the marker for a large bookshelf...don't think...just buy and thank me later.
