Thanks, guys!!!
I asked Srajan to test out the Sig 30 with his Gallo Ref 3s (this are 87dB or 88dB), so they'll present more of a challenge in terms of efficiency than the Zu Definitions.
He'll also will let it burn-in some more and will then continue the review. So far, all is good!

Thanks again for all your support! It is MUCH appreciated!
Best regards,
