Some amps have a natural roll off due to their design NOT due to any signal processing. Want to learn about amp design go read the stuff Nelson pass is writing about on diyaudio.
No amp has a flat response from 0hz-infinite hz. And due to no physical components being perfect either there can be ripples in the frequency response. There are arguments on the audibility of lots of these things. But that being said a clone probably isn't going to be all that great run up high.
Also there are two kinds of signal processing. Analog and digital. Amps only include analog sp when it's to protect from dc voltage or ultrasonic noise. That sp happens outside the audible range and has no impact on what you will hear. Dsp is becoming more common but it has to be explicitly states that the amp has it.
In other words the Frequency response of an amp is due to design and component used not some screwy signal processing conspiracy.
Also there are experts here and lots of the guys with high posts counts can be called near experts or in fact experts. And you will see the usual players being asked for advice and helping people an providing info. And rule 12 of the internet - lurk moar! Lots of the guys know more then you so instead of trying to school us just sit back and listen. You've already demonstrated ignorance so most people here won't take you seriously until you show some respect and start to learn some of te FACTS of sound reproduction instead of spouting off nonsense that has most of us laughing at you.
