greeklover: I have been researching for pc speakers and a lot of people suggest something from Edifier. They are pretty expensive, maybe one of the basic series is good enough for you.
I'm a happy user of
Edifier speakers for like 3 years now, even though is a cheaper model (R980T). Hopefully I'll change it for a better model like R1800BT or R2000DB, which I find having the most pleasant sound but seem a bit bigger to keep on the desk.
Nope, I don't think they are expensive for the sound quality they offer. Expensive are Bose, Klipsch, Audioengine and the like. Microlab is another good brand with fair prices
Here is a
youtube channel with very good audio comparisons between various speakers - use headphones to really tell the difference.
