Hi! I am new here, and I did it because I like very much music and cinema, and I want to combine both introducing myself in the well known now home cinema systems... I have right now: cheap dvd player. Sony cdp-xe 530 Sony str-de 135 Magnat Motion 60 I want to buy another 2 speakers like I have (I have read that it is important that they are all the same because it gives a more balanced sound), and a central speaker from Magnat (in total, 300 euro). I wonder if I really need a subwoofer, since the speakers range over all the frequencies needed. I have been told that it is, because the low frequencies go only to it, when you decode the signal. Is it not possible to redirect it and put them to the front speakers? The second thing is to buy a receiver. I want to enhance possibilities with the home cinema, but I don't want to get worse simple stereo sound than before (str-de 135, sony). After looking and asking a lot, I saw two or three possibilities in two money ranges: a) Range 550 euro, it can be Sony str-db 870qs, Kenwood KRF-V 7060 (or 6070?), or Yamaha RXV 630. I like very much this last, specially the rear panel looks very complete. About sound, I couldn't hear them yet, but I will (of course!). I am almost decided in favour of Yamaha, in fact. The question is, are they balanced to my speakers and cd-player? Or it is too much? (I mean, you may have a great amplifier, but if the source is not good, and the speakers do not sound, you get nothing). b) The little brothers, of the previous, only in Yamaha or Kenwood, Sony doesn't convince me from some opinions I have heard. That is, Yamaha RXV 430 (or 530, 100 euro more), and Kenwood KRF-V 4070. Both are 350 euro. I have heard the Yamaha one, and I found it simply great. But then here, will I loose stereo sound quality with respect to my present amplifier? I hope you can help me, than you!!
