Тому я поцікавився у оглядача з Unheard Labs (unheardlab.com) щодо порівняння Аюн до Фіоо і він у коментах до огляду мені відповів: "I’ve actually been testing the JT9. I think it’s good, though there’s a bit of deja vu at this point with the FT1 Pro, JT7 and now JT9 all sharing a fairly similar platform. The JT9 feels a bit like an updated FT1 Pro to me, with most of the differences coming down to fit/build and some slight tuning differences.
For daily use without EQ I’d prefer the AR3000. It’s lighter, more comfortable, and I enjoy the stock tuning more. With EQ I might prefer a good JT9 pair since distortion is lower, and planars tend to be more tolerant when it comes to leakages. But that also depends on getting a good unit. Fiio has had some QC variation here with some pairs run into excursion/clipping issues. Overall sound quality is in a similar ballpark, but the AR3000 is just a more enjoyable package to me."
