I have not, but just want to make a general statement.
I believe the JE LA 150 mk 2 or 3 is around 7-8K, while
the LA-300 ME is like 15K. A good phono stage w/ either
of these would be another 5K. Shouldn't you be comparing
these to a Massetto or V-R preamp. None of my business,
but comparing these to an Aurieges wouldn't seem fair.
