I use amperex bugle boy primarily or its Philips and valvo variations. The German valvo are equally good. Also When
i roll them it with a tungsrum that is very nice. Both seem to me very balance presentation. Mullard and clear tops are also very good depending on your tastes and equipment. I have tried the telefunken but for me they are a cold sound. Have not tried modern types as I have a lifetime stash of nos. The candela is one of those animals that is very balanced and allows for a wide variety of tubes to experiment with.
