I can't find any common thread if I search for:
Best amplifier 2023
It's just random different amps that are chosen by various different HiFi magazines, HiFi websites. So if
What Hi-Fi? favors British manufacturers/products/advertisers should it shouldn't it be the same for other actors?
Based on the conditions that exist for these actors, which country they are active in and so on. A hypothesis anyway and I don't think it's too conspiratorial to believe this.
Edit:
Okay, those who are focused on, for example, tube amps, retro vintage or whatever it may be, will of course nominate some ditto amp as the best in 2023. Fairly obvious and hardly a unique observation to make.
