I have never had a problem with home use, being short in output at the wall outlet. Obviously the more you go to having a pro like system in the home, the more outlets you will need to add to your system. The other point being most power over 1000 watts per amplifier/ driver, even in a completely heat less 100 percent efficient design, if it existed, would be wasted in the fact the the addition of more power is simply unable to provide any more real output............ Ie 10 times the power just to double the sound. Requiring 10 times the effort just to double the result at that point is inefficiency to its max no matter what amplifier you are using.
The smps argument for efficiency along with many other arguments, go to support the manufacturers goal, of converting all customers to the CASH COW products, now made, in which they intentionally incorporate self redundancy to have more sales in the future.
Not many people have had to replace a crest ca 18
That being said.... the real benefits of light weight make huge logistical savings, in less resource consuming mobile setups. This is the only real reward from SMPS, but unless you move every week, its not likely this benefit will accrue any savings to home users.
A Good amplifier requires a adequate power supply, It does not matter what the amplifier is capable of if the power supply will not provide the power required. Most amplifiers have under rated power supplies. It is up to you to make sure you get the ones that are least under rated if at all.
