That could very well be Adam.
We had one person who came to our office with a set of good [non-horn] 2-way bookshelf speakers with 6.5" woofer to compare to the HB-1's. He and Dr. Hsu listened to these bookshelf speakers and HB-1. This individual felt that the HB-1 sounded more nasally in the midrange in comparison, while Dr. Hsu felt exactly the opposite way and felt the HB-1 sounded much cleaner and less nasally in the midrange. And I know that I've always really liked the HB-1, even compared to other very well regarded low cost bookshelf speakers, but it's not everyone's cup of tea.
It's just amazing how listening impressions can be so diametrically opposed between two different people listening to the same speaker!
At the same time, something could have been wrong with the HB-1 that mazer listened to. I know that something was amiss with Tom Andry's first HB-1 pair that he reviewed for Audioholics (maybe shipping damage, or something else), and when he received the properly working pair he said that they sounded and imaged much better.
Note that the current shipping HB-1 has a significantly upgraded tweeter compared to the first run of HB-1's too.
