Class D amps seem poised to take over. Then what?

I am certainly biased by my lifetime final amp being a Class D. But I know that after 30+ years of development, Class D seems to be on a high plain. I know there are now many, many companies focusing on Class D and, maybe, a good handful already as good as it gets. My Class D amp is as smooth and beautifully musical as a great tube amp and as punchy and detailed as a great SS amp. I am satisfied and done with my search. A class D amp has effectively taken me off the amp merry-go-round. It’s about time after 50 years. And, for me, this Class D is a milestone. Will all other classes of amps fade away?

Next you’ll say an OTL of Ralphs can drive those Wilsons to their best properly, because they too will stay stable into them and not oscillate.🤷‍♂️
atmasphere
The sales manager of Wilson had our amps for many years. FWIW our OTLs are inherently stable and will not oscillate with any load or input signal condition.

Dream on sunshine, were talking about driving the Wilsons mentioned here.
Trust you to try to skew it around to make out that your OTL amps could even come close to driving these, the hardest of Wilsons to drive
(Always looking for the self promoting angle)

Keep your Dingos away from him
What does that even mean?


Anger issues, I'm guessing.

@invalid.FYI.  These guys claim that wattage doubles (close enough) at 4ohms. 

Pathos Classic MK III
Specifications

Type: Integrated amplifier in Class A/AB, hybrid circuit with input tube stage, bridgeable
Output Power: 2 x 70 W @ 8 Ohm, 2 x 130 W @ 4 Ohm, 180 W @ 8 Ohm in bridged mode (mono)
Inputs: 1 balanced XLR, 4 unbalanced RCA
Frequency response: 2 Hz - 100 kHz
THD: <0.05%
Signal/noise ratio: 90 dB
Input impedance: 100 kOhm


Pathos LOGOS

The Logos uses MOSFETs in the output stage, known for their tube-like transfer characteristics, in a design that attempts to come sonically as close as possible to Pathos’ patented InPol circuitry. InPol is the only amplifier design, hybrid or solid-state, that gives the full glory of a tube amplifier but with control. Look at the numbers: 110 watts per channel into 8 ohms, and an amazing 220 watts into 4 ohms, with full bandwidth

It wasn’t mentioned
Let see what happens into 2ohm un-bridged. (bet they can’t handle it) and those Wilson’s mentioned hit 0.9ohm!!!.

You keep mentioning Wilson's as being hard to drive, where does this come from? I have owned Wilson's from their beginning starting with the original Wamm's and i have never found them difficult to drive even using 300B tube amps. It seems that you lack personal experience with Wilson. https://www.stereophile.com/content/wilson-audio-specialties-alexandria-xlf-loudspeaker-measurements
