Studio monitor - active or passive

too vague. cant help

in the meantime i thank you for your intervention and anything that is suggested/reasoned by you is always and in any case an improvement.
then, to be less vague... i will explain better why active speakers are not in my strings. being someone who likes to play the #stratocaster guitar, i often go to a well-known and very large warehouse where there is every musical instrument on planet earth. in the audio department there are well-configured stations with different types of active speakers available. there is everything and a couple to which you can say, wow if they sound good, there is not. from here, also to set up a home made station, i invented a hybrid LS /3/5a, that is using one of my many boxes that i built myself, inserting recovery drivers. (see my Use a different... topic) Starting from this and leaving my two reference amplifiers (Jeff Rowland & Carver M 1.5t) in the hi-fi system, I thought I would get a sound of a certain level also on the PC station, which I will also use as a measurement station, to measure my DIY initiatives that I cannot avoid. I've always had them, I'll never recover. 🙂
 
While you made a good point in general, this above is not the complete truth. I’d rather say, the loudspeaker-room interface is the weakest point.

I think that in the chain the weak points are cascading, that is: if the source is terrible, the rest will cascade down to the speakers and the room. If the source is excellent, then it's the amplifier's turn and that's where my problem falls! In my opinion the active speaker amplifier is poor and will never be able to make a pair of monitors sound their best like a real amplifier can.
 
I agree with markbakk in this case and the reason I can't agree with what you've proposed is because the distortions produced by each stage are very different and they don't compound.

I'll give an example, one distortion is to hear sound reflected from different angles.
 
there is no doubt about this, I also agree with you on some things, but I believe that a quality amplifier has all the credentials to drive better than a class D and that in addition to the tonal qualities and better control of the medium-low range, it puts the speakers at ease in reproducing music.
