I'm considering 2nd most "powerful option", for 1x 4 ohm driver per side.

Bur then, even 2x for £1800, is far cheaper than used Powersoft K20.

Think K30, 35 and AD 42 need to be tested by that group member. Personally don't  think AD 42 is much more powerful than other two given the price difference  between them.

Perhaps factor in retained value and re-sale value when looking at equipment costs.
You can buy a used K20 today that has basically done it’s depreciation, use it for a year or two and sell it for more or less what you paid.
What is the retained value in equipment that is not serviced by the manufacturer, has no major market demand and is effectively a door stop when it goes pop?

Every China special amp I see go up for sale used in the UK seems to sell for more than what they actually cost direct from supplier LOL I think people are just trying to avoid oversea shipping I am not sure, it’s a strange arrangement for sure haha! If they are to go bang though you are completely right then

these amps are all modular with a power supply board and two output boards. think it's about £150 for a new board and is very easy to fit.

got a quote on AD430 of 865USD, 160USD shipping.  K410 585USD (presume shipping is the same).  Big datasheet numbers! the most interesting test to me would be long term maximum output with all 4 channels loaded (something 1u amps struggle with due to heat).

As long as you remember, 4x channel lightweights, are not designed for sub on all channels.

Not even the illustrious X8.

eh I bet it would be fine with a 'real' 4 ohm load (which is reactive and has loads of peaks spending very little of the range down at Re) and 'musical' content (IE not just a sine wave).  4ch amps are great for sub arrays.

Be intresting to measure/ listen to two chan 4k amps, and  also the 4 chan 4k amps, output cards are the same, but powersupply board much bigger, so guessing the two chan would put out more sustained bass energy  then the 4  version can
I use mine bi amped so bass top split across the 4, never all 4 handling just one duty, and only into 4 ohms, so nothing gets hot

actually I would revise my opinion a bit if its as weak as the X4, I think that needed something like 14dB crest factor to be capable of full output in the long term in the production partner review.  Plenty of non sub things load the channels with in our systems though.

Thats all good.
Will boards still be available in a few years time? My experience with Chinese manufacture is they are always after the next big thing and ling term supply is difficult
