I know there are a few players with both a Bergantino HT322 and some type of all tube amp (either head or combination tube pre + tube power). This cab is rated on the Berg website as having sensitivity = 104db anechoic: 2.83v/1m, which should be plenty efficient. But on the other hand I recollect some saying that it takes a lot of power to "Wake it up". What's the tube scoop on these? I would love to have a DB359 head, but don't want to have to buy another (or more) cab(s). Might be just as cheap to get a DB680 pre and use my PLX1602, but I doubt it would be quite the same as all tube. Y'all let me know what you think. Thanks.
