I agree with Feivel.
Chazzonus as a form of entertainment outside the shul is one thing, but in the shul it is a plain tircha if it leads to a lengthened davening where some people just want to hear the chazzan and as such are coming to a concert rather than davening.
The words are just as uplifting if they are recited by a recent BT for whom it is his first or second time at the amud as they are if recited by a chazzan who is paid to perform. If anything, deep down I know the chazzan is a paid performer and I doubt very much whether he davens with as much kavana as a volunteer. Instead, he worries about whether he is going to be asked back to the shul for another lucrative RH or YK gig.
