Crisp sounding tubes for Modwright 5400ES

Jwm,

I was amazed at the difference as well! This tube alone will make an average 6SN7 sound splendid...

If you're still using Mullards in your power supply, you're missing crucial detail like vibrating cello, violin or guitar plucks, deeper/wider soundstage, longer decays and the overall satisfaction of almost being at a live performance.

I have over 500+ hours of constant use and I will say without hesitation the Create/Synergy 5AR4 are better the my 1960's Mullards.

Wig I agree, I still can't believe the difference like a whole new system. I am using the Sylvania VT-231 Fat Boy 6SN7 in the main unit and love the sound. I wonder how the Create 6SN7 would sound?

I wonder the same thing and I'm using Sylvanias Jan-Chs VT-231 with excellent results but hear the Create 6SN7 are very good.

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
