Crisp sounding tubes for Modwright 5400ES

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.

To me the create is much more open, faster, and more dynamic. The Mullard slows things down.

I let the create tube burn in for 3 days per distributor/seller. It sounds better. Midrange glare is gone. Some upper treble hardness that reminds me i am listening to a digital facsimile is still present. While it has more apparent spatial and micro resolution it isnt as analogue sounding as my mullard. Worth the money and worth keeping? Most definitley. A different flavor compared to Mullard. Cheers.
