Spectral 30SL SHHA upgrade


Any Spectral 30SL owners out there who have done their upgrading to the latest SHHA module? Care to share the sonic benefits? The 30SL by itself is already a terrific sounding preamp, just wondering how much better it can be after the modifications by Spectral.

Thanks Greg for your reply. Can't wait to have mine back. Now you got me all excited!! My dealer had kindly offered to have his set for the interim which I declined. I only want to have my baby....Will keep you posted when I get my back.
Just got my upgraded 30SL back. The sound is superb. Very refined and controlled. The music that flows is so effortless and sublime. Thanks Spectral for making the upgrade possible.
