If someone no longer enjoyed owning and using an item they had previously been very happy with because a few people made some derogatory comments about it on the internet, that doesn't say very much for the product. Or for the confidence the owner has that he made the best choice for himself.

BTW, I didn't get a chance to comment on the Kenwood system because the thread was closed before I read it but I must say I agree with you. Assuming my guesses about your taste in music and your level of interest in audio equipment performance are anywhere near the mark, I'd say your system is the best you can get for yourself and you shouldn't look for anything more expensive or complex. For your needs and tastes, it is the best you will ever have.
