The website looks very slick - kudos to your web team and contributors.
Some initial impressions/recommendations:
Company Tab: it would be nice to capture the philosophy of "no better / best" but rather just all top-line products with different features/functionality. Also, perhaps a sub-tab that goes into the history of Bryston - how the company was founded, by whom, how the name was established, what was the first product and perhaps the lineage of products leading to the current offering. Finally, perhaps a personal statement / committment to excellence from the CEO and something on the current executive structure.
Technical details - I see the links to these are dead currently - I'm sure just because work is n progress. Would it be possible to ensure that each product has a one page summary of their technical specifications - perhaps a specification tab. And, would it be possible to build in a product comparison tool allowing for side-by-side comparison of products by type e.g. amplifiers, that would make clear the key differences in features and specifications.
Gallery - along with the product pics that I'm sure will be added shortly, would it be possible to add a Gallery tab that would include pictures of say the products in owner homes, at shows and in other applications - perhaps some studios. I'm sure that some of those on you client list have provided / permitted photos of their implementations. This is also a place where any product/marketing video links could sit.
All the best with it!
