Audioholics is a pretty good place, IMHO, that dispels a lot of myths.
Here's a pretty good article on why audio amplifiers can sound different.

I just went through a speaker upgrade. I did audition the speakers I was considering, and I found a set that sounded good to me - and even my wife can hear the difference between the new and the old speakers (the old ones were 20+ years old - technology progresses).
That said, I agree that audio is a personal taste. Some people like speakers that I don't and vice versa.
One thing that I have found in the past is that a cable can matter for DVI. In any cable, one has to deal with wire resistance. If that resistance is too high, the signal transmitted over it will not be strong enough even if it is a digital signal. In the DVI instance, I had a 9' cable with a high wire gauge where the picture had sparkles in it. I bought a cable 9' cable that had a lower wire gauge and the problems disappeared. The same can apply for HDMI. However, that does not mean that one has to pay a lot of money for a cable that has a lower wire gauge, thus less internal resistance and lower loss. I have found it sometimes difficult to get the specs on the wire gauge used in the cable, though.
On the audio end, if the cable is of sufficient wire gauge to transmit the signal with minimal loss, the audio coming out of such an HDMI cable will sound no different than any other cable of any cost that meets the same basic specifications when it is in the same system. But you all already know that.
The audio/video shop that I deal with most of the time is one where they don't offer much, if any BS - I value that, and they know that they get my business because of that.
