My dad has some older speakers that I would want to pick-up and use. The problem is over the years the amp that came with it got broke.
Now I'm looking into using them with my computer (laptop). So I'm looking into amps and preamps that would make everything work together. Problem is I'm not that good in this stuff and I would like some feedback from you guys.

The speakers are a pair of Bowers & Wilkins (B&W) DM580.
Specs:

- 2 x 8" composite fibre mid/base drivers
- 25mm aluminium dome tweeter
- Power handling: 10 - 150w RMS
- Impedance: 8 ohms
- Sensitivity: 91db

Do you guys think that these components are compatible? Will this setup work if I plug it into my laptop's headphone jack?
Thanks!
