#174 Stax SR-L300 Limited Discontinued eBay

Pros: Crinacle’s measurement gives it a very good Harman preference score of 75 with a 2.99 dB spread. Its tonal tilt of -0.12 sits close to the target, so the overall balance is neither dark nor bright.

Cons: Discontinued, so it is mainly found used. Its 2.99 dB spread is less even than the best measured sets.
