I didn't know what forum to put this in so I apologize to the moderators if they have to move it.
After going through some of the literature in the Sound Science forum, there is quite a bit of skepticism regarding the ability of Amps and DACs to affect sound quality despite many, many testimonials to the contrary. Let's assume that they don't affect sound quality or provide equalization as a baseline.
Is it scientifically possible to change the sound quality of a recording through an amp or do any kind of equalizing? My admittedly noobish understanding of amps is that they essentially just raise volume and gain. But the basic design of an amp is not to change sound quality but just to increase volume, correct? Or am I missing something?
Thanks in advance.
