I'm using an MHDT Stockholm which is cut from the same clothe. I have the GE5670, WE396a and a Bendix. The GE is a nice all around tube. The Bendix brought lots more detail and upper frequency extension. The WE is superb in all areas so that one is my favorite as well. I've only tried these 3 tubes and have no interest in looking further once I heard the WE. The WE is Reasonably priced to boot.
