Hi,
I'm looking to buy an amplifier for around $2000, I have the Elacs Uni-Fi 2.0 UF52 paired with the Yamaha A-S801 and the subwoofer SVS SB-1000 Pro. The Yamaha A-S801 has wakened up my Elacs and now they sound more lively and clear, I'm happy with the sound but I know I would love to have an amp with similar power but a warmer and layback sound. I know there is a big debate about the topic of pairing, YouTubers talk about amp/speakers 'synergy' but I'm not sure if is real or not, but I'm for sure want to hear suggestions, buy some of them and try them at home, so I could make up my own mind.
Please don't fill up the chat with back and forward debates if amps can color sound, and change tonality or not. The reason for the post is that I want to find the answer for myself, I feel I'll love that type of sound and I will do an at-home blind A/B testing to achieve this.
I'll be buying this speaker switch but I wish it had another input, to switch the subwoofer as well.

I will truly appreciate any suggestions for warm amplifiers.
Thanks in advance

There is no magic about this, just hard cold facts. If an amp is warm it has a frequency response error, if it is cold/harsh it has a frequency response error.
Your Elac speakers are not warm, above the average for commercial speakers of that price, but they have a flaw which you object to, and its is a frequency response error.
I have been in audio for almost seventy years now, and have always designed and built my own speakers, and learned a lot in that time. My observations are exactly that of other experts.
When I left our Lake home in Northern MN I took the equipment of the AV room I had built there with me, and installed it in out new home in the metro.
Now the new owners of our lake home asked me to install a system in the old theater. Since I was busy building out a new room in our home under construction, I had no time to design and build speakers for them. As it happens I selected your very speakers for the right and left speakers. They wanted to purchase form Best Buy, and after reviews and based on the reputation of the designer, I selected those Elac speakers. Unfortunately at least at that time there were no third party measurements.
When I listened to the speakers they were above average for speakers in that price range, but they did encroach on being just on the side of harsh.
I had my equipment with me, and I had time to get at least an on axis measurement.
These measurements are quasi anechoic. So you can not be overconfident of the results below about 200 Hz, but you can rely on them from 200 Hz to at least 15 KHz.
Now you will note a 3db rise between 2 KHz and 7 to 8 KHz. Now even the slightest rise in response here will make the listener reach for a warm button if there were such a thing. So in order for an amp to do what you want it would have to have dip of 3 db in the above range.
Now many have noted that a rise in FR is far more unpleasant than a dip, especially if the rise is between 2 and 5 KHz. The BBC noted this years ago, and in order to play it safe designed BBC monitors with a dip in that region. This became known as the "BBC smiley." This practice was widely adopted by many British speaker manufacturers, and some still follow the practice. It does produce a warmer more laid back sound.
So you will not change your situation by changing an amp, because no self respecting amp designer is going to release an amp with a frequency response error of that magnitude.
If you had a receiver with Eq, you could try and pull that range down 3db. Unfortunately there was a snow storm coming so time did not permit off axis measurements.
Equalization can not guarantee perfection, as it will affect the axis and off axis responses equally, which may not be what is required. That is why equalization does not always provide the results expected.
This was the response on axis of my speakers in the same room before I sold the home.
This image also contains the axial responses.
You will note that both mine and the Elac speakers have that rise at 50 Hz, and that leads me to believe it is a room interaction.
The same speakers in my new AV room, which is a bigger and optimally dimensioned does not show that 50 Hz rise.
So to cut to the chase, unless you are extraordinarily lucky to find am amp with just the right frequency response to be the inverse of your speaker aberration you will not solve your problem. You have more chance of winning the lottery.
The bottom line is that these dissatisfactions of the type your describe can be universally explained by good frequency response measurements. The combined axis and off axis FR, and the resultant in room power response is the most overriding and important determinant of the quality and character of the sound you hear. There are other determinants, but if the FR is not dead right, then that aces out other virtues. I would say, that every one truly experienced in sound reproduction would agree with that statement.
Unfortunately there are opinionated clowns not schooled in science who dredge bilge from the backs of the necks sowing endless confusion and falsehoods.
I have given you the facts.
