Alan;
As you and Ian have suggested, I checked all of the settings on my receiver and used the subwoofer.
I think that what Randyman stated is true. After listening to low quality speakers for so long, I just need to get used to the new sound. I am enjoying different types of music now just to be able to hear the crisp and clean
sound from these M60's.
I would like to thank everyone for their help. These 'open' forums are a testimony to your belief and commitment in your products. I find it quite refreshing, if
not a little bizzar, to be able to communicate directly with
'the owner'.
