What I hear with live music is sound that is really relaxed. It may get loud, but even when it does, there is no "cringe" factor. I think most audiophiles would be put off with this kind of "relaxation" in their home systems.not me anymore!! I've learnt that this is the sound that I want from my system & it will be capable of delivering such a sound when I will find components that will keep the phase distortion down to a minimum. That's the reason I turned to 1st order x-over speakers which, when built correctly, are time-coherent speakers & finding electronics that is as true to the original sound as my budget could afford. Having had such an experience you find me endorsing time-coherent speakers every time I can. I've managed to FINALLY sway a few people on this forum that time-coherent speakers is the way to go after THEY heard time-coherent in THEIR system & agreed with that it was the only way to proceed.
Getting an amplifier that is as uncoloured as possible i.e. within one's budget is the right thing to do because an an accurate system will always be a true system long-term.
Try sitting down in front of a good unamplified string quartet, or a solo classical guitar, or a front row seat right in front of the string section of a full classical orchestra sometime. Its like a breath of fresh air.AMEN!!
That's because there is no phase distortion from the electronics & esp. the speakers. What you are hearing are the fundamental tones + their harmonics directly from the various instruments with no electronics to muck that up. Such a delivery of sonics is *always* welcome & will *always* sound right not matter what the person's age.
