#427 Stax SR-X Mk2: $120 Discontinued eBay
Pros: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap.
Cons: Measures far from the Harman target (preference score 46), so most listeners will hear it as colored; EQ can correct much of this. Discontinued.
Is the Stax SR-X Mk2 right for you?
Skip it if
- you want a neutral sound without EQ (Harman score 46).
- you need isolation or will use it in public: open-back headphones leak sound both ways.
- you want to buy it new: it is discontinued.
