Didn't NotNyt replace like 8 bridged Class-H 5000's with 4 burst Sanway 14k's at one point, I could very well be Mandela effected though, so maybe I am misunderremembering.

We are starting to go off topic again. But:
The XBS 20k is better than the 22k (IMO...)
The 20k has MANY of the traditional black plastic transistors (which ALL the other clones USE), where as the 22k uses only a FEW of the metal-top transistors. Hence why it blew up on NotNyt when he tested it at the limits!
I can't speak for the 22k as I don't own it, but I don't notice any difference between my Sanway 14k and the XBS 20k, if anything the 20k is more powerful, but that could just be my inefficient MalX-21's (that need to be thrown in the trash
I've pushed all sorts of sinewaves and sweeps and basshead music through my clones and NONE have failed or muted or turned off or done anything BUT produce power. YMMV.
I watched the newest Ape Planet movie this Christmas at breakneck levels, and the amps were fine. I've NEVER heard a movie played LOUDER in my life. The bass almost cracked the projector bulb NO JOKE!
There are members on this forum that have broke their subs playing the basshead music I enjoy, regularly...
The continuous power on those songs are only bested by like: BassCannon, and not by much...
I highly doubt your music is more aggressive...
The power supply in the clones are a TRACKING design. It only consumes and produces as much power as is needed to reproduce the signal, where as Class-H amps only have a few gears to shift with, making them less efficient (for starters.)
The bridge rectifier in Class-H amps are generally the limiting factor. Most companies cut corners, massively.
It's possible to have enough parallel bridge rectifiers and toroidal windings to provide enough continuous-power but they NEVER do it!
Class-H maxes out at 49% efficient, and the XBS are in the 90's. The heatsinks and amp can be half the size and still be fine. The Crown5000 is like 5000watts of heat for 5000w of power (bridged mono).
The clone is like 800w of heat for 8000w of power, it also has 16kW of burst (or whatever...)
I would get 2 20k's for 8 21's, that is closer to "ideal", but you can do whatever makes you happy!
If they are 4-8ohm and not 1ohm IPAL's, then all should be GOOD!
That said: One can never have too much power!
8 bridged 14k's ought be enough for anyone!
