I'm asking the aged brains here - I bought an old AKG 451 E off ebay - clearly liquidated stock from a failed audio company - but mainly because 1. It was black and all mine are silver, and 2. it had the metal slide on basket windshield. From the pictures it had a CK1 cardioid capsule.

I know the E version of the 451 mic doesn't have the roll off switch.
But apart from this, do they sound exactly the same or is there any difference?
Both using the CK1 capsule.
