Both prior suggestions are noteworthy and other possibilities are yet to be explored.You mention about the sacd format.If you have one of these players as I once had,then from extensive researching of many posts and audio reviews,one needs to burn the player in for 500 hours for each of the 2 formats for the optimum in sonic satisfaction.If you play at a very loud listening level,then this will add to your problem,as well as will the acoutic nature of your room.
Source of Brightness
I have rigning ears from the brightness in my system. Linn Genki, Meas Baron, Magnepan MMM (1.6s ordered). What is the source and solution? Robert Harley in TAS on SACD said that the CD brigthness/harshness wasn't there on the SACD and in the past the best CD players balance brightness with detail. Are high end makers walking a tight rope due to an inferior souce format?
