Do I need a preamp after MiniDSP 2x4HD? 1 month 2 weeks ago #56929

Hello there,
I'm currently using MiniDSP 2x4HD -> Passive Preamp -> Power Amp in my system.
The passive preamp is just for source selector and volume (no gain).

My understanding is the benefit of Preamp (Active ones) is to amplify and stabilize an output level a bit (e.g. to 2Vrms) before sending signal to the power amp.
So the question is, is there any benefit of using an actual preamp (MiniDSP -> Preamp -> Power amp), or would it downgrade the sound quality than without preamp?

Thank you for all your response.

You would only need an active preamp if you need voltage gain and/or cable driving capability.

In your setup, I don' t see the need for a passive preamp, nor an active preamp.  Assuming you can get sufficient system volume without them.

And assuming you do not want a manual volume control knob.
