Best High Current amplifiers stable into low impedances
Seems like all I hear when reading Stereophile’s measurements when it comes to speakers: must be used with a High current amplifier stable at 2 Ohm. Most amplifiers rarely give specs related to 2 ohm loads. Most amplifiers are only stable into 8 and 4 ohm loads, and if they mention 2 ohm it seems they aren’t saying continuous, but peak, short term power.
With speakers becoming more complex and harder to drive, what are some high current amplifiers that have no problem with these 2 ohm or lower impedance speakers?

agree w @ghdprentice from a practical p-o-v for users sorting through amp choices, the best indicator is if the maker clearly states the amp is able to double wattage from 8 to 4 to 2 ohms... another indicator, less good than the first, is if the amp (at least traditional class a or ab ones) are big and heavy with substantial power transformers and heat sinks - delivering consistently high current flow into low impedance loads generates mucho heat |
we can talk amps that can deliver gobs of current into low impedance loads (op's query asks for what's best in terms of 'stability into 2 or 4 ohm loads') but separately we can also talk about amps that sound terrific doing so b is very much a subset of a, let’s not mistake that speakers like thiels maggies etc need the power/current but they are also very revealing of the sonic quality of what is being fed to them solving for a does not necessarily solve for b, for best performance, need both |
