New E.A.T. small signal tubes

Anyone have experience with these? Are they worth the price?
I just had two EAT ECC803 for a trial.
IMO very good tubes. In direct comparision with Telefunken 12AX7 smoth plates I prefer the EAT.
EAT - more dynamnic, more detailed top end, great midrange.
Telefunken - more 3D soundstage.
Thanks for the feed back. What are their tonal character? Anyone else tried them?
They are very neutral and musical. I use a pair off ECC803 with Primaluna prologue Two and they make a huge improvement to the supplied 12AX7 valves (Chinese, I think).
Now the sound has a much more refinement and musical character. They are better extended at highs, with much more information. The original valves are a bit congested in the mid to the highs, what make it a little aggressive in some records. Now, the mids are clear and smooth.
Bass is different too. I would say it has a better tonal balance.
They are expensive, but once you customize to the better sound, you don't want go back.
Thanks for the replies. I'm using NOS tubes in my preamp now. I will give them a try next time I need a set.
