I've used all above mention tubes in my ARC SP11 MKII.
Telefunken E188CC by far is best sounding in the right placement. What I mean is they sound best at phono section.
Extend highs and very nurtual sounding. But if you placed them on line and play CD it sound hard edgy and little bright.I end up with Amperex 7308 JAN in the line with E188CC in the phono.
