I have no current xperience with the CAL IconHDCD Power Boss but I did own one years back. Sold it in 2001 and bought in its place a Meridian 508.24. The Meridian, which wasn't exactly new in 2001, trounced the CAL in every area except one- the CAL's bass was better. Can't imagine thar a CAL Icon would stack up well against a current $2000 to $3,000 digital front end
