It is for certain but I along with many others prefer the old 555. It's also cheaper. one cap change to remove the weirdness in the ultra low end on the mkii model costs about $3-$5 and I've yet to hear anything for tons more that beats it. Adcom put a 3.3 uf mylar square box shaped cap to block DC so the sound is affected, the amp is ever so slightly bass shy, but replacing it puts it in the class of the pass labs amps that cost 10x more. You aren't as likely to hear as much of a difference between how differently designed amps drive speakers with axioms because they do not present a difficult uneven load. I miss having easy to drive speakers like my m22tis

I would go so far as to suggest that any receiver that has a switch for 4 or 8 ohms, or states "compatibility" issues with low impedance speakers is a cheap design using either dirt cheap final output stage transistors or a power supply made to be very tiny so a ton of other junk could fit in a small box. It's like saying I am not "compatible" with benchpressing 400 lbs, when the reality is I am not strong enough or in good enough shape to. There is a difference!
