The least expensive products were probably in the headphone rooms on the top floors. I was not really looking for any new headphones.
Only headphones I listened to were the Audeze LCD-MX5's and they are not budget headphones. They are the next step up from my Audeze LCD-MX4's, and not that large a change in a short demo.
The ELAC room was probably the most budget room and sounded good. Did not spend much time as I am not a box speaker person.
