" The best is the enemy of the good " ; what else?
BHSE + SR-009 is the best headphone audio system (in production) in the world; sorry, Lau + Abyss is the best headphone audio system in the world; sorry (again), Orpheus System is the best headphone audio system (out of production) in the world.
Who is right for the best headphone audio system? Personally I don't know.
By cons, what I know is that listening to the SR-009 and LCD3F with Luminare amp is (probably) not the world's best headphone audio system but provides two very good listens; perfectly complementary, each providing a (very) great listening pleasure (with the same amplifier).
So, what to choose, regardless of the price of the system: the
best headphone audio system providing for each better system, I do not doubt it, a great listening pleasure (at least I hope for homeowners), or a
good system, more universal, for listening to both two very good headphones (complementary) each with a great listening pleasure (not least of one compared to the other, but equal and complementary).
In short, what is best ? or what is good? Two listening pleasures or only one ?; You choose.
