Electro Harmonix valves vs...


I've been recently introduced to EH tubes to use instead of Svetlana that I use right now as EL34 by a dealer. He has Kora mono amps that use the EH EL34 tubes. I've listened to these amps and I loved them but I'm still not sure if these tubes are superior to Svetlanas.
Had anyone had an experience to play with EH tubes?

I agree with the Svetlanas being better.Have both prefer Svetlana by far! Thor 30 watt tube monos.
Update: Having very excellent results with Electro-Harmonix KT-88's vs. Svet (SED) 6550C's. And apparently this EH KT-88 is *not* the same tube as the Sovtek version. (I haven't tried either the Sovtek or the SED KT-88's ; nor did I try any 6550's other than the Svet's.) Live and learn...
Update:
Tried EH valves in my VTLs. They have better bass controll but its reliability is totally unaccaptable! Will never ever use them again.
Currently use 6CA7 yugoslavian fat bottles flowlessly with advantages of both: Svets and EH.
