Crisp sounding tubes for Modwright 5400ES

Just swapped the Create Audio rectifier tube for my Mullard. Can't say I am super impressed. Will let it burn in for a while and see if it changes. Right now I would characterized it as:
- no more resolving than the Mullard
- introduces an upper mid-range glare
- introduces a treble hardness that reminds me I am listening to digital
- less even and coherent sound stage laterally
- only positive is I do pick up some slight increase in reverberation cues (better sense of space on some notes) but also notice a flattening of some microdynamics at same time

Podeschi,

It will get better over the next few days of run in. The Mullards will sound congested in comparison but you'll notice more subtle cues and textures never heard before on CD's you listen to the most.

Thanks Wig. I have my modwright on repeat.

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.
