Unfortunately in the current audio press there is about 90% bunk. So what you read makes you more ignorant than before you started.
This is a forum that will give you the straight scoop. We have members here with many years experience, over 60 for me.
The first thing to get straight is that the speakers, and the interaction of the speakers and the room will create the sound you hear.
Having said that good speakers are far less fussy about the room they are placed in. There is a good reason for that. Most domestic rooms have good sound for conversational speech. If you had a musician in there playing an instrument with a singer it would likely sound OK. If not it would be hard to make any speaker sound good in it.
Now what makes a speaker sound good is now pretty much well known. Like musical instruments there is the sound that reaches you directly and the speaker is wholly responsible for that. The rest is reflected sound. The further you move away from the speaker the more reflected sound there is compared to direct sound. So in this area we have a combination of speaker and room.
Now the flatter the frequency response and the closer the off axis response of a speaker mirrors the axis response the better the speaker will sound. This is well established in listening panels.
Now the ear expects to receive lots of reflected sound, and the ear has lots of leeway in what it will tolerate in terms of reflected sound. What is does not like is a huge discrepancy in tonal balance of direct and reflected sound. That is a huge issue for a large number of speakers. As well as being sub par, it makes them very fussy. The other issue is that it is a myth that it can all be made right by EQ or changing amps. As Billy Woodman of ATC points out, frequency domain errors in speakers are almost always associated with retained energy in the mechanical/acoustic system and can not be put right with EQ.
There is one more issue that is of importance in making a speaker sound natural, and that is its damping or Q. A speaker should be well damped and not resonant. When the sound stops, the speaker should stop also. Many don't and have prolonged impulse responses. This also makes them fussy, as it will reinforce room resonances in the bass decade.
Now you have your room, and your speakers. It is fruitless to find an amp that will change the situation I have outlined.
So the speakers will sound the same in your room with any competently designed amp of sufficient power.
There are probably not many integrated amps that will do justice to those speakers. However one company really stands out in superb integrated amps and that is
Creek
If you power your speakers with an amp of impeccable quality like that and don't like what you hear, then you bought the wrong speakers.
Before buying speakers subjective BS reviews are worse than useless. Auditioning helps.
However the most useful is extensive third party measurements. To understand these you need some fairly extensive education.
There are so many bad speakers out there I say it in unwise to buy a speaker without an audition and or right of return. I personally would be reluctant to buy a speaker without extensive reliable third party measurements.
Bottom line is that if you buy a quality amp and don't like what you hear you bought the wrong speakers.
Here we are not going to snookered into discussions of whether amps are "Chocolaty or velvety" with said speaker. That is the stuff of fantasy and self delusion.
