faced with same problem here!! Ipod equalizer + DSP + Tone... if i put the rock settings on Ipod and DSP, it is multiplied my 2, so i get extreme bass and twitter... I can't flat out the IPOD cause i use it for jogging and home system... So i try to flat the DSP, but since i have a casette adaptor to the Ipod, i don't want to rely on the casette for inputing my preferences because it is not that reliable.. i want the main unit to control the preferences... plus the overall tone settings... very tricky!!

Any recommendation? by the way, i put the some fading to the rear, since the front ones are closer to your head, giving a little more power to the rear will increase the surround effect...
