Altec - late models including 510 tower. Quality?

Would like to know if anyone has ever tested out a pair of Altec 510's from the newer release in the late '90's. I have a pair but haven't matched them up with proper amplification. Can anyone tell me if they have the potential for excellent sound?
Geez I should check in on my computer more often.
I'm too busy working and listening to music.
I really like this series.
Some people really hate this series.
I've got several different models of these
and they all like power.
The bass can be a little loose with low
power amps.
A 150w is probably the minimum you should
look for.
