Maybe, but suggest you do some math and then share.
I build custom Hypex/Purifi amps. Buying a single case is a major expense and (nicer ones) can have major lead times currently. Unless you readily cut holes for connectors and switches, need to add fabrication costs too. YMMV but DIY may actually be more expensive.
Sure, it might be more expensive but it might not- and as I said, there is value in getting exactly what I need. The new hypex ps looks to be an improvement over the old one as well. The jury is out until more details are released, that's why I am now on the fence.
