Yesturday i brought Pioneer sx-302 and Elta LS-200, i tested it today and the quality of sound is great, no problems at all except a little bit of heat on top of the receiver, so i started digging about it and i found out that receiver is actually 8 Ohm and on speakers it says they are 4,-,8 Ohm .... so i wonder maybe that is the reason for heating??? is there any danger running those speakers with this receiver ???
