Good afternoon, I'm a new member and appreciate being a part of this group. I purchased the Mcintosh for 2 reasons, the second of which is the ability to use the speaker output terminals for everyday listening without headphones. However, I can't get any sound to come from a set of KEF LS50 Meta speakers. I believe they're rated at 4OHM and for those that know, would that have anything to do with not receiving any output as the amp's rated for 8OHM for small or large speakers. I received an excellent deal at Best Buy for a new, sealed box MHA150 but without the ability to use the speakers I'm unable to use it for much use for which it was purchased. Help is greatly appreciated.
