I have a measly Schit Freya S that sounds pretty neutral to me and I believe has published measurements that bear that out.
The 3 way adjustable gain including passive mode is a nice feature to help match to various amps!
Neutral preamplifier recommendation $1K new
Must have: Active, remote, two XLR inputs and XLR output.
Units I’m considering.
Denafrips Hestia
Ladder Bach
Schiit Kara
Topping Pre90
Vincent Audio SA32
Looking for a unit that measures well & has no/little sound of its own. Right now I’m leaning towards the Kara.
