Because you said cheapo sets, transformers, and 200k in an inexperienced way. The best SETs are the lowest watts so they have the least amount of parts in them so they are the least expensive in cost of making.
Any inexperienced person can hear big amps with big speakers pump up the volume pump it up pump it up at any major hifi store, hifi show, and random audiophile. It takes experience to hear a very low watt set drive a speaker to full symphony. Given the small amount of speakers they can drive, you have to search. It won’t come easily
moreover, there are many talented people who can make way better than commercial speakers at way less price but that requires search.
Did not ask people to. Don’t expect you to. Doesn’t change the fact that people who think 200k plus speakers are better, lack experience on sonics or have incentive in propagating that idea.
In future, please post videos of 200k plus speakers you think are playing well. What records, music, and gear you select will say more about your experience than price tags.
