I would say add something which will work with everything to enhance the sound..And can always be of value. Thus I suggest a good power conditioner.Speaker changes may mess up the sound you already like.One thing to worry about is messing everything up, particularly if you are happy with the sound now.Also knowing WHEN TO QUIT! screwing around matters. Particularly if you are happy. Changing stuff can and will make you dis-satisfied and unhappy just as likely as happy.
Where do I go from here?
