Dusty, not this weekend but some other time sure I did not do the L3000s since I generally like to ask owners before I defile their headphones by measuring them
I was thinking about it today and I'm worried about the unit I have failing and being without or the unit going out of production so I'm planning on getting a second one to sit in the attic as a backup.
Maybe that way I can get the power supply caps changed out too because apparently they fail sometimes.
