Not happy with Krell SACD

I have listened to about 25 cd's and a limited amount of SACD's and I am not satisfied with the sound of the Krell SACD Standard. For whatever reason it is far too bright for my ears. It is actually fatiguing at times and I do not want to listen for more than a few minutes. Has anyone found this to be true or have another opinion? Do you have any suggestions?
