unbeatable Class A integrated

What’s a bit of a pill is listening to people’s opinions and theories about things they’ve seen pictures of. That’s a bit of a pill.
And by the way, George, the 509X came about after the 590. The fact that they ’look the same’ has zero bearing on the engineering or design of the L-590AX. Point us to some links of all the burned up/failed Luxmans, you know, the ones that you're convinced can't possibly operate properly for any length of time. Gotta be all over the web, don't ya think. Last word is yours, not wasting my time with another ounce of your drivel.
Cheers,

George,
Why would it be surprising if they look similar from a 10,000 ft view, which is what each of those images you posted basically is because we can’t see details of any of the circuit boards?

All I am talking about is the 590axii anyway and all I am claiming is that it puts out at least 30w class A and based on two independent bench tests at least 90w total into 8 Ohms.

FWIW one of the bench tests indicated words to the effect of the 590 operating substantially in class A over that 90w. I’m not sure exactly what that means but anyway the only contention was that it twice tested to 90w (95w in one test if I recall). Even if it is 30w class A and next 60w class A/B, which at a minimum seems to be verified by the only two bench tests we have, that is still great.

The comparison to 509 is a separate issue and not one I’m concerned with (maybe others are)

Whatever, the doubters obviously have not done much work on amps to see it. (can't see the forest for the trees)

Not true. Fact is most techs (I’m a EE) wouldn’t make any such assumptions without knowing more about the internals and specifically what components are used to populate the circuit boards - sheesh! Those images tell us very little.

iPhone models tend to look somewhat similar too if you ignore important details but ......

If you read what I said.
"Fact is any tech will tell you these amps "look" to be the same" save for the differences I mentioned.
Look!!!! to be the operative word here.
Like I said you need to see the forest for the trees.
And "if" your a decent EE if you could see that it so obvious, as they look to have the same circuit topology.
