Please explain. As far as i can tell it's just alot louder but thinner, which fits my opinion of switching amps.

@ specialjustin, what I said is the switching amplifier Itech, have poor performance above 1Khz, especially above 10Khz, alot of limmiting and distortion, compairing with the older Macrotech series. Also, Macrotech offer sustained output power, even in 2-4-8 ohms loaded, regarding Itech wich offer big BURST of mSeconds power, finally it can sustain 39Vrms on 4 ohms dummy load (around 400watts/4 ohms sustained, but big 2500watts peak burst power...)
What all of us must understand, is, on today market, they want quantity and profit, quality is on second or even third place, unfortunately...
Compare old school CROWN Macrotech 5000VZ output waveform at 20Khz, at any output power till clipping prag, with the CROWN Itech 5000HD, you'll see alot of distortion, wich the users with "cleanner ears", will tell, the sound is innacurate, no transparency, etc, they are right!!!
That's the difference between years, first they watched for quality and andurrance, today, I let you speak bout' it...
So for bass duty , if we cam use class D , class I or Class TD and classH 2-3-4 step. I personally recomend for mid hi range , purity of AB class.
Need more power, use bridged amp and that's it. Edited by DjLeco - 07 June 2011 at 2:57pm |

So...who has experience with a lightweight amplifier that can compete, or better, surpass, the sheer muscle of a Crown MA5002VZ? And if so, can you state what it is, so others can give reviews too?

Nice one DjLeco, i didn't really understand alot of what you said, what with your broad Norfolk accent an all
But what was going on in the last clip...what a racket that Itech makes, like an airplane taking off!!

Very good explanation Peter!
If you want to see how performs Macrotech 5000VZ into dummy load, and severel frequency, look here, I have done alot of tests:
Macrotech (old school amp)
8 ohms testing:
2 ohms/30Hz testing
4 Ohm 100 1000 10000 20000 Hz
8 Ohm 100 1000 10000 20000 Hz
And New School Itech HD series, same power rated, but cannot sustain it, as you will see:
and poor acting at 20Khz and 10Khz above too
