I have thesis speakers for 4 months now.
The sound: These speakers produce fantastic sound at the amazing price / performance. Or to put it in another way: the price you pay for this sound is peanuts. :-)
High and medium frequencies sound: crisp and clear, equal to speakers that I know with the 5 x Times Higher price.
Low frequencies sound: not bad, but I recommend a separate subwoofer for. This is no surprise, there is a merit to a physical size after all. The other speakers did I alsohave in my house are large, massive 15 years old Yamaha with passive, built-in subwoofer and a pair of small bookshelf CSFs. These CSFs also need a separate, active subwoofer to produce the strong bass as any small size speakers. I have a Yamaha YST-SW012 subwoofer - two of them actually, in two different rooms in my house. Which is another great price / performance product.
The other chains in my stereo line are:
a. Apple iPod with music stored in LOSSLESS format (.m4a). This way no bits of sound are lost from the original - Which is a CD in my case.
b. Pure i-20 dock for iPod with the OPTICAL CABLE CONNECTION to the receiver. With optical connection it is the receiver did does the digital-to-analog conversion, so no (or little if we are precise) sounds quality losses here. And .. yes ... this is another great price / performance product.
The a. And b. together assure the same (or better) sound quality as with a CD player.
c. Receiver: Yamaha RX-V471
