avid_pro_tools_hdx_hd-io_system_fI recently updated to Avid Pro Tools HDX system, retiring my much loved and used TDM system.  Audio quality, processing, latency and sonic quality are all far superior to the old system.  Add to the mix, an upgrade to Pro Tools 11 and I can definitely say that projects benefit from the added quality, clocking and features of the new cards, interface and software.  An added bonus is the ability to integrate completely all of my analog gear easily and quickly into Pro Tools mix projects.
