If you can power 4 drivers off a single amp better than you can power 4 drivers off 4 individual amps, it makes sense to do so.
Now to put this in an example you likely will still fail to grasp.
Running an SP2-12000 and powering 4 LMS-U 5400s off that single amp will have at least the following benefits compared to running 4 of the CV5000s.
1) more power output
2) increased efficiency (this has many benefits, less load on power source, less voltage drop, etc)
3) less ambient noise
4) less heat
5) less wasted space
6) 22 lbs vs 333 lbs
7) less points of failure
8) less idle power draw
Regarding efficiency, if you only have a 20A circuit for example, and are running an amp like the CV which is around 55-60% efficient, for every amp you pull from the source, almost half of that is being given off as heat. You use 20A, 8-9A of that is going to heat. If you're limited by your power source, you just lost 3db of potential output as heat. Compare to the SP amps, which I've tested at 93% efficiency. You use 20A, you're only converting 1.5A to heat. FP14000 will be 4A wasted as heat, which is still twice as good as the CV.
I can't really make this any more basic for you. This is not my limitation in explanation, but yours in understanding.
Actually all the failures are yours, where you simply only want to look at your side of the equation with your opinions and views, and say , everything is better your way.
Firstly speaking of what amplifier one owns means nothing, as you change your amplifiers all the time, for whatever
reason, and as I said in another 10 years you will probably change a few more times before I do. The amp will die or you will sell before that happens.
Old school value................ Im still using 3 Yamaha mx 1000 all my pairs of main speakers, whichever i choose to operate at any point in time. This will be 30 years in use in another five years lol. Now they may be only 260 watts per channel, but they power any speaker I have ever owned to the max no problem, and usually i need not use more than 35 watts. Because I have always owned amps with digital output meters, I have always understood what power level i was using at any point in time and what DB level that corresponded to. Unfortunately most simply turn the dial, and thing they are using more power than they really are........... Now when you compare this to smps which would be lucky if they all averaged 7 years. This is a savings of 4 amplifier replacements.
Now going to subs. I have never ever needed to 2 ohm load and never will. Simply never did require the power. Maybe with only a couple subs in sealed condition i managed to use full power on two bridged cv 2800. Now that they are ported..... A move you made with all your subs despite all your raves of , I GOT POWER. Because i bridge load, as i have posted before the result is like explained at leonard audio..... The most efficient way to use an amplifier is in 8 ohm bridge mode. For a small sacrifice in watts produced, you get a XXXX load of power, with only half the voltage on the rails. The amplifiers never break out a sweat this way.
I will be here on AVS with all my amplifiers in 20 more years they will be 30 years, and they will all be working. Not to mention they will probably be worth more in scrap metal by then than i paid. 800.00 an amplifier is dirt cheap.
With 20 subs now and over 1500 lbs of amplifiers lol. I can tell you that in my room, because of the amount of displacement i am using. I need not go anywhere near full power on any amplifier. Something else that comes into play when deriving longevity. I have simply overdone it. I need a bigger room lol.
All the time you brag about your smps, of which 96 percent are bad, just like the other guy posted........ when ditching out 6 smps amplifiers in one sentence. I do use 6 lines to power my amps and as much as i would like them all to be 20 amp. I have zero worries about breaker blowing. Two ohm loaders can accomplish that, but as i explained many times I will not have 1db extra output switching from 8 ohm bridge loading to 4 ohm, which is really 2 ohm loading.
Obviously everything I have done, i have not done by following some other persons way of thinking, and we need not forget that Insane people that go this far in audio, just to do some bass in the home, are definitely one in a few hundred thousand at least.
My audio has always been good...... I sold all my internet stock two months before the nasdaq crash of 2002. I purchased 10 homes in depressed real estate markets with that, that are now with 10 times what I paid. As far as I am concerned I am doing things right, and if lots did what i did for their home audio, they would save a fortune, is not be stuck with dead clones , and dead smps and might have some extra cash to put in the nasdaq at the right time.
