This is the question I've tried to find answer for...
There is much talk about how good amplifier design should ideally double wattage per ohm halve, for example 100 wpc 8 ohm should ideally be200wpc to 4ohms. However, very few amplifier actually do this, even most High-End brands like Luxman, Accuphase etc fail to achieve this in most of their amp designs.
Which let me thinking, is it really, really necessary to have this on amplifier? People usually listen their music at few watts at most, sometimes achieving briefly perhaps 10-50 watts.
Lets make an example:
All tree given amplifiers from same brand are identical (aside from different toroidal trafos and secondary capacitors), minimum impedance of listened speakers to be ~4.5 ohm.
A: 100wpc to 8 ohm, 150wpc to 4 ohm (very common)
B: 100wpc to 8 ohm, 200wpc to 4 ohm (very rare)
C: 100wpc to 8 ohm, 100wpc to 4 ohm (imaginary example)
should these amps equal identical musical experience, because 100 wpc to 8 or 4 ohms is never exceeded?
Or am I getting this wrong?
