Very pleased with these speakers and its product, since I did not want to spend 400 euros or more ... We have to grind these speakers (lapping is important and quality of copper son too, between the speakers and the amplifier), the sound changes a lot (positively, of course) after 30 to 50 hours of running, refer to specialized sites on the Internet. I can not really say more, I think it's the sound of my PC chipset (average chipset motherboard MSI Z87-range of G45), which prevents a perfect sound - or even more beautiful, say. I'm no expert. In any case, my PC configuration -> amp Yamaha R-S300 -> these speakers, it's fine with me (I can still improve, I think with a dedicated high-end sound card for PC, Creative SoundBlaster type Z ). That said, if you can to budget more than 400 euros for a pair of speakers, you may find what suits you from Bose, Triangle, Yamaha, etc. But if it is for PC use, you also need a high-end sound card to enjoy it, and correct amp - spending 400 euros enclosures to recover a PC via its basic Realtek chipset, no thank you, there, it would be wasteful. In terms of budgets around 100 euros, that's all that I found! (Ps: these speakers do not connect directly to a PC)
