穷人HIFI真能听上头？曹伟A1甲类复刻×达尼博睿1拆解：证据全在里面！

In this episode, we’re stripping "Budget Hi-Fi" down to the bone. We’re looking at the Cao Wei replica of the Musical Fidelity A1 Class A integrated amp paired with the DALI Oberon 1 bookshelf speakers. Why exactly does this setup sound so stable and clean? This teardown isn't about "audiophile myths"—it's about the evidence. From the power supply and signal paths to critical component choices, we’re laying out every reason why it sounds this good. On the speaker side, we aren’t just counting components on the crossover; we’re looking at how a legacy manufacturer’s tuning philosophy is actually implemented.
