Musical Speakers that can provide dynamics for HT

Looking for musical speakers that have detail, accuracy and a sweet midrange and highs for female vocals but are dynamic enough to do a good job on home theater. Room is 17x19x8 1/2. Starting with a 2 channel system that will grow into 5.1 HT with an emphasis on music. Was thinking about Thiel 2.3, Revel F30 or Merlin VSM. Thiel requires a lot of clean current to sing, F30 won't pass WAF, not sure if Merlin will do HT well? Not many dealers in my area to demo. Any comments regarding the above or other suggestions would be appreciated. Please provide amp suggestions with your speaker recommendations. Will spend up to$4000 on used speakers.
