Thanks for all the respone. I would like to add more information for my question.

1. I listen to female vocal and Jazz most of the time
2. Listen in a small - mid size room (150 sq feet) with low volumn, usually at night.
3. My price range is around $2000~$4000 used speakers.
4. Monitor or floorstand, does not matter
5. Resale value is also important, since I have experience to buy some good DIY audio stuff but hard to resale.

thx
I'm currently using a pair of Energy C-3's with my 15W tube amp. They're rated at 90dB in-room efficiency and I have a small listening room. Wouldn't recommend using anything under 90dB with an 8 Ohm impedance.
Omega Super Hemp is very , very good. Zu speakers are nice as well. You can add Emerald Physics CS2 for it awesome performence - with EP CS2s you will need another amp for low frequencies. PS makes nice $1000 mini amp 150wpc I think. Be carefull with your choices. I have almost made that mistake with my 2nd rig. Being prefix on M&D speakers could have end up in a very bad missmatch. I auditioned them with my own amp and indeed it was a crappy duo. Audiofeil was right - they needed power and lots of it to sound their best. One leson lerned. Do not make that mistake. 90db and above is my advise.

Good luck
