Any cable will change the sound, and this is due to how the unit's power supply, along with its input and output impedances, interacts with the cable and power cord. So, how any cables will sound in any of our systems is unknown until you use them. Do you have to spend crazy money on cables? No, but you should buy quality-made cables.
A lot is to justify the prices asked and have been designed for their looks, as much for sound quality, and for audio gear, it is the same.
I heard systems 40 years ago that sounded like real music with no exotic cables in the system or power conditioners. So, I always keep that in mind. But they do make a sound difference when used right? We all can hear that. Scopes have nothing to do with interactions within our system’s gear where they are connected, thus interacting with each other as a whole.
Amir’s view and his followers is audiophile gear claims made are false; well, I say more marketing for sales with terms that, at times, make me laugh. They play on our ignorance of cable design or even gear, so they can make any type of claims they want to make. What they sell today is so much better than what they made before. They need sales to stay in business. At the end of the day, we are talking wire here, nothing more, nothing less.
There are always people who want to hear what Amir has to say to justify their view that we are fools. Well, we all cannot be fools if you buy gear and hear a difference. There is no absolute sound, because everything is colored; it’s what you enjoy that makes it the absolute sound for you, and that’s all that counts.
The best sound investment is in your room acoustics and making your room audio-only with a proper speaker setup.
