Tubes in the Unballancer

I tried 12at7 Golden dragon as front tubes in my unballancer,and it sounded real nice maybe a little laydback in the top,so I tried JJ 12at7 but it didn´t sound nice at all....
anyone have any experience with Electro harmonix 12at7 and philips 12at7?
Or any other brand as well how do they sound?
