“I don't think that they are broken in yet but they definitely sounds better than the stock Prima Luna”

“Received a pair of these tubes quickly and in good condition. Rolled into my Prima Luna Integrated HP and run for 50-60 hrs. They sound good and I have no complaints. I assume that the "military" designation indicates more robust filament support and general shock resistance. They are replacing a pair of low time NOS Brimars' for now. Well, they are not going to banged around so the extra shock resistance is not going to be tested. They are not noticeably better or worse than the Brimars' or the stock PremaLuna tubes. They all sound outstanding in this integrated unit. FWIW, this is my first tube stereo amp so I may not be as keenly critical of a listener as some more experienced audiophiles. But I know what I like and I like this amp and these tubes.”
