Ei vs Electro-Harmonix KT90


Has anyone heard both of these tubes? For my listening I have always preferred Ei. But I have never heard this new EH KT90.

opinions?

Hey Trelja

Don't be fooled buy the results of your tube tester. I find new production tubes must be changed every year to year and a half regardless of what the test reuslts are. When I do so the difference is astounding even if the tubes test over 90%. Comparing 5 yr old Ei's with new JJ's is not a fair comparison of these tubes.

Buy another set of the Ei and then do a comparison again I think you will be presently surprised. Assuming both sets of tubes are well matched, non microphonic and in good condition the Ei I think you will find will out perform the JJ by a wide margin.

They certainally do in my rig.
I have tried both these and while both are very good and are the best current production output tubes I've heard. The Ei takes it in my rig not even a contest. The Ei's have a tightness, clarity and 3D image that the EH cannot compete with.

The EH did however produce a little more slam and bass so the type of music you listen to and your listening habits might weigh into it.

Personally I'm willing to give up some slam and bass to hear more about whats going on with my tunes.

Enjoy you music
Yes, the old Tesla tubes form the 70's were very good if you can find them in shape and at a decent price. I believe they took over from Mullard when they got of it and used there tooling.

As far as current tube the Ei is ano brainer IMHO
