HYPEX vs ICEPOWER

ICEPower, because they have a MUCH bigger footprint throughout multiple markets with a long history of reliability and regulatory compliance.
...and with you being someone who has a long history working with the ICEpower design group I value this as an extremely credible, informed answer and not just an opinion.
 
Somehow I remember that Hypex had widely available modules before IcePower did, though the Hypex modules didn't have integrated power supplies. Building a conventional power supply wasn't such a big deal for home audio DIY'ers. Integrating the power supply and power amp kinda seems like where rubber meets road for making a compact bass amp. The power supply designer can no longer blame the power amp, and vice versa. ;)
 
Part of it was that ICEPower has always been ahead of the curve for safety and EMC compliance. Without compliance backup documentation and support, certifying the end product can become a nightmare in a hurry.
 
Hypex show their compliance in the datasheets.

They are for many products now, but this wasn’t true say 10-15 years ago.

But, TBH, I've no idea which one is better for metal :D

Though I can well imagine, why to a commercial amp manufacturer looking for an OEM amp module, B&O backed ICEpower constitutes a lower commercial risk, especially in the early days of class D amps.

ICEPower was spun off by B&O many years ago, though B&O still uses the technology.
 
There's also Pascal which is used in the Trickfish Bullhead 1K amps, but none of their other models, all of which use ICE modules. I always thought that was an odd data point in their lineup. Many users report the B1K (Pascal) and the B.5K (ICE) sound different, but that's almost certainly down to implementation more than any single component.

Many people report that the 1K does sound different from the .5K. Part of that is the preamp design goals, and certainly part of that is the power delivery of the ICE versus the Pascal.
