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?

Not mentioned are spectral amps.  Had the studio model and drove anything including Maggie panels.   Sold the system when I downsized.  Lack of dealers, slow and picky customer service were the reason not to go back to the brand

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

@jasonbourne52  Perreaux 2150B - 340/680/920 wpc @ 8/4/2 ohms.

The manual says 200 wpc into 8 ohms. Could you confirm that? Could you articulate its sound traits? Its damping factor sounds reasonably high but the continuous current of 10 amperes per channel seems a bit low compared to modern amp. Thx.

@atlvalet  Aragon 8008BB 

Do you know the current spec of this?  Seems not available in the manual.  Again, could you articulate its sound traits?  Thx.

 

 

 

From the user manual of the Pass Labs INT-25 integrated amplifier:

The amplifier is stable into any load which does not dip below 0.5 ohms, but it will protect itself by shutting off any channel which outputs more than 10 amps (200 watts peak into 2 ohms)

Remember, the Pass INT-25 is rated at only 2x25w per channel but its stable down to 200 watts @ 2Ohms :) Not all watts are equal watts

I have often thought Pass Labs XA series would be a great amp to drive a 2 Ohm load, but they don’t publish any specs into a 2 Ohm load. I was ready to jump on a pr of XA 160.8 but was unsure they would drive my Focal Maestro speakers. The Focal’s have a schizophrenic load; it’s all over the place in the upper bass and lower midrange. 
I’m currently running the new Luxman M-10x amplifier. It drives the Focal’s well and sounds good, but there’s a feeling that the Focal’s need more.
