Hello guys .I just took back a rotel rb1090 power amp and a parasound halo p-3 pre amp. The bass was to weak. some one told me to go tube on the mids in high. and go solid state on the lows I am just sick of going back and forth I want my speaker to kick ass when I turn my volume up, and when the volume is low I still want to hear my bass, smooth mids and nice details crips highs. I did have two crown dc 300 but one keeps blowing transistors. I gave up on it. so I need a rump shaking back busting bass amp any info. thanks gene
