voltage vs current

[Raj1]

Hi,

does anyone have experinece in how lower voltage rails with higher current bias affect sonics of an amp? I have a high biased PP mosfet amp, at the moment bias is around 580ma with around 72v at the rails. Just curious if anyone has dropped rail voltages of an amp whilst increasing bias current and noticed an improvement, or compromises of other qualities?

Thanks
Raja

Depends on circuit design.
