Re: Ipr2 5000/7500?
A couple of thoughts on amps in general.
It was said decades ago "What we really need is an amp that will produce 100 watts continuous and pass 20dB peaks". That would be 10,000 watts.
I totally agree with that statement-and that seems to be more the norm in todays amplifiers-large amounts of voltage swing for short periods of time.
HOWEVER_NOT all music is the same. With "normal" music the above would apply. BUT WITH modern dance/EDM/Rap etc, the low freq duration is CONSIDERABLY longer than the 20 or 40 or 80ms that have become "standard". WIth the sustained tones and very low crest factor-you need an amp that can produce power for a longer period of time.
You also need to look what happens when the amps "settle down" to a lower power and how much power they produce long term-say 3 or 4 seconds.
Now how important this is-REALLY DOES depend on the style of music and what you are doing with it.
Some of the "monster-well respected amps" just don't do as well as others when it comes to these types of signals.
Just something to look at.
It is kinda like speakers-one of the things that manufacturers don't like to talk about (what does it actually sound like at those levels-at what freq is the coverage pattern etc), and they like to focus on the short term power output.
As usual-you have to dig a bit deeper to get the real useful answer-at least as it pertains to you and your usage.
It is also quite interesting to me the number of people I have meet who have already made up their mind about something-yet have never heard it and when faced with the truth-simply refuse to acknowledge it or come up with excuses to try to defend their position-however wrong it may be.
Listen to things with an open mind and THEN make a decision. But there is so much "brain washing" and "wanting to hang with the crowd", that many people put their blinders up real quick.
