What the BGVP Astrum does well: The median of 10 hobbyist measurements gives it a very good Harman preference score of 77 with a 1.49 dB spread, and its mids sit within about 1.5 dB of target, so vocals and instruments sound natural. The catch: Its 1.49 dB spread is less even than the best measured sets.
