I have no view on Ponies, or Bronies, but FWIW, I used a borrowed Mana Reference table for a year or so. I thought it had a certain 'tidying' effect on the sound of my LP12, but later realised that it was taking away more than it was giving IYSWIM.
Still, horses for courses etc., and apart from being, to quote Alan Sircom: 'A right royal PITA to keep clean' it looked OK.
OTOH 50 or 60 'phases' (That particular pretension still makes me chuckle) of Mana do seem to invoke a look and an atmosphere reminiscent of the back of a bread van after the round is done.
As for stainless Mana. They've obviously sold out and bought into Glam-Fi
I mean, if you're going to make a big ugly pile of angle iron, mild steel is the only honest way.
