О наушниках Kennerton Veritas, Rognir Dynamic Valkyrie и Arkona. Звучание и апгрейды

I wrote a review of three new Kennerton headphone models. I also discussed the upgrade program, which allows you to upgrade your existing headphone to a new model for what I consider a reasonable price. I did this with two of the three headphones I'm reviewing. I also touched on the topic of sound sources, which I'm particularly concerned with. But I'm not sure the idea of ​​messing around with op-amps is for everyone.
