Crisp sounding tubes for Modwright 5400ES

Podeschi,you are hearing something much different than what I heard. I got my Create tube last winter and put it into play while it was still cold from being in the mail box. It was really good from the start. It could be you got a bad tube.
My tube did not change significantly with burn in.

Podeschi, my tube also was good from the get go. I am using the Oppo 95, but using the same tube.

Ok I will chime in on this one. I just replaced my RCA (Mullard) with the Create tube. It sounds about the same as the Mullard, not worse, so I need to let it break in before I can really decide if it's that much different.

I either have a bad tube or my ears are telling me Mullard is better. Or Create isnt broken in.

Poseschi. The Mullard tube is very good. In my system, the Create was better. I heard none of the bad things you heard. It is possible that the Mullard sweetness has better synergy with the rest of your system or is more to your taste, but the relatively poor performance with respect to spacial clues tells me it is a bad tube. If it were me, I'd ask for a replacement. If you don't like the replacement, I guess you have your answer. I had heard that Create had problems with a batch of these tubes a while back, so it does happen.
