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?

One thing in favor of the EI - it's reputed to be a very rugged military tube that will last a long time. I own the "Type II" variety and really like their clarity in mids/highs. I preferred them to EH KT88s. Haven't heard EH's KT90 variety, though.
