Serious Passive Preamp question


I have a Audio Research LS7 Line stage preamp and someone wants to trade me my AR LS7 for a serious passive preamp
Is anyone familiar with this company ?... I was told it retails for $2200.
 My  Amps are Class D wyred 4 sound mono blocks.
Opinions please.

I'd never owned a passive preamp until the Schiit Freya came along...the passive option is interesting, but the tube stage has the gain my single ended amp needs. The output switching feature in this preamp seems most useful (to me anyway) as a way to see what the tubes are doing...
