6ER5 Tube Question - Wright WPP 100 Phono Stage


I want to understand why this particular tube was used by this audio designer when no other designer/manufacturer seems to have done so (to my knowledge anywway). It is a significant curiosity that I have as an avid audio enthusiast.

Is there anyone on this forum whom might have spoken with George Wright regarding this phono stage and has an insight as to why this particular tube was used?

Opinions and guesses are also welcomed. Thank you

How about a quote from the Listener Magazine review, May/June 2002 about the 6ER5 tubes..."George Wright says he uses them primarily because they avoid the "degenerative capacitance" (up to 240 pf) that can result in high frequency deficiencies with other, more common high transconductance triodes like the 12AX7" Peter Breuninger closes the review with this... "I think this is one of the best buys in audio, and certainly one of the very best sounding preamps I've heard, at any price.
