Hi Dave,
Yes, completely agree with you: 'if you haven't got a problem, don't go looking for a solution', especially if the 'solution' could be a waste of money.
How are you getting on with adjusting the position of your speakers to provide a stereo image further away from the TV? You need to 'toe' them in as Chris (The Grand Wazoo) has described. Your 'eureka' moment in discovering the stereo effect, caused us great delight on the forum. A little more work and you will complete the task.
Regards
Barry
