Rush R30 is a very poor recording/mix from the audio side,from Emerson TO Krell,nothin can help that.Of course as to sound thats just my opinion.Rush has had recording issues for some years,even studio.There is a site somewhere but I forget where that tested several later Rush cd's and the actual recording were clipping very badly.I am a big Rush fan,2112 remaster is outstanding on the 990.
