Blue Aria MC phono amplifier

I’m expecting the arrival of this unit, which goes by the full name of Blue Audio Systems Aria. Very little information is available on the net, so this appears to come from way down the rabbit hole.

This is a current gain device (or ‘transimpedance’ as some would call it) that was designed and built ca. 20 years ago by Reto Andreoli. This guy keeps a very low profile, but his name should ring a bell as the designer of the Magic Diamond mc cartridge.

Any useful information is appreciated. Opinions are welcome, but facts are better. Thanks!
