I'd be curious to know your amps input impedance as at or near max attenuation would be very loud.

Spatial Audio Raven Preamp
Spatial is supposed to be shipping the first "wave" from pre orders of this preamplifier in May, does anyone have one on order? Was hoping to hear about it from AXPONA but I guess they were not there. It's on my list for future possibilities. It seems to check all my boxes if I need a preamp.
