The Plinius is high gain (32-38), espescially when using XLR inputs or when bridged. That's one reason I chose it along with a passive TVC line stage and compatible source (good Vout/low Zout/ direct coupled). An active preamp with 20 dB gain would be useless, possibly detrimental, on moderately sensitive speakers. There are some active pre's with gain as low as 10 dB. Pass comes to mind.
