Again, another excellent review piece, mate.

Nice review as always, agree with your last part about pricing on single DDs. Shouldn't cost to much, even an custom made driver will not push the price up in the sky.

Though I have one that is coming soon that is slightly high cost, Miroak-II

@Leonarfd oi, congrats on the 643ears! I learnt a lot from reading the blog of the tuner. Looking forward for your impressions!
