I hate to say it, but I prefer the old site. The new site feels like a generic e-commerce site that happens to sell audio gear.
I mentally block out the Selection Guide and Learning Center areas on the left side of the page because they look exactly like Google ad modules.
There's lots of content on each page, and each bit uses the same font size and each could be covered completely by a half-dollar. I understand that on the front page you want to give a user many choices as to where to go, but there should be a clear place for my eyes to land when glancing at a specific product page. On the old site, I also liked that all the product info was displayed all on one page. Multiple clicks to go between Overview, What We Think, and Specs is now a pain, and hides the helpful descriptions behind multiple tabs. The 'What We Think' section for each product is the most important content on your site (for me), and it seems like its been hidden from view unless you hunt for it.
The blue and green color scheme is not pleasing to the eyes. To me its neon-ish, and reminds me of an 80's rollerskating rink. For me, it enforces the cheap, generic feel and kinda makes me dizzy. (I'm not a very good rollerskater
)
Lastly, product mix. Not long I was a newbie at audio gear and felt overwhelmed with the choices and information available at head-fi. I was relieved when I found headphone.com. It felt like a resource that had already done all the research for me and only presented the best options. Before I felt comfortable telling my friends to take a chance on a new product at headphone.com because my 'buddies' there felt it was good enough to endorse. Now, I'm back to doing hours of my own research before making a purchase decision.
For me, the new site no longer projects the feeling of 'trusted partner' for audio gear advice, but now takes on the role of one of many places that might get my money after I do my own research and shop around for the best price.
I hope I'm not being overly melodramatic, I just want to provide some honest feedback.
