The ultimate is Direct Injection. No analog ears etc - just direct injection into the appropriate brain cells.
Best thing is - you won't go deaf. (No more grasshoppers or cicadas - yay!)
soundman - I still don't get the Ohmage as related to higher power. It is easier getting more power with higher voltage than it is with higher current - ie, increase the Ohmage.
I certainly don't recall low-Ohmage speakers in the old 40kW music PA systems - I think they were 8 Ohm as were speakers in Marshall and other guitar & music amps.
Sute, they had the luxury of AC voltage (110-240VAC), but with the advent of SMPS for 12VDC systems, that is now irrelevant.
I'm sure a 1kW sub at 4 Ohm would sound better than 1 Ohm - the only difference being a 70V rail as opposed to 35V rail at 4x the current (and 16x the heat; smaller filter caps, etc).
