Does anyone have experience with the Mass, MiniMass, and Load Dumps? I'm about to sell my Barber LTD and get some sort of attenuator. I'm anyone has experience with these products and could tell me the difference between them.

Also, other questions regarding Weber products: What of the Z-Matcher (impedence converter) vs multi-tap OTs? Is the former as much a tone sucker as some believe the latter to be?

Can an attenuator be used as an impedence converter? (The OT is seeing the attenuator, not the speakers, right?)
