There are a slew of reasons why the sound gets harsh at higher volumes. Unfortunately, many of the reasons are off of many audiophiles' radar screens. Consequently, addressing the usual suspects such as room anomalies and "mismatched components," while somewhat ameliorating the situation, do not eliminate the harshness.
Likely culprit for harshness at higher volumes?
Hi,
I'm a newbie to higher end audio. I have a very modest system:
1) Pre-amp: Anthem AVM2
2) Amp: Adcom GFA-5400
3) Source: Sony CDP-X111ES CD player
4) Speakers: KEF C75
5) Toslink between source and pre-amp; cheap RCA cables from pre-amp to amp; 16 or 18 gauge speaker wire (Radio Shack?)
Room setup (10-ish feet x 20-ish feet rectangle):
1) 2 foot deep cabinets along one wall (20-ish foot)
2) Components stacked on top of small end table against rear wall (10 foot); centered between cabinets and opposite wall.
3) Speakers slightly in front of end table and about 2 feet from side walls and 4 feet from rear wall
Sounds good at about -45 to -25db; but higher frequencies get harsh at higher than -25db.
Appreciate your thoughts.
