Peter,
I got the SACD and played it last night. Given that it's late in the evening, I only played to the level of -25db on my receiver panel so there is NO WAY that it's too loud. The surround is awesome, especially the "storm" track. But I do encountered problem/issue: When I played the 1st track "Blast Off", I did not hear the normal jet/rocket blast off sound. Rather, I heard when I thought was clipping sound coming from my M80. I don't think I played the track loud so now I am worried. Does your CD have the same "blast off" track?
I will post in another a/v forum to find out if that was what the track supposed to sound.
