Preamp or not.

I currently have the following setup Bluesound Node 2I, Topping D90, Pass XA25, Crites Type B speakers.
I originally had a Sunfire preamp but it failed. Then I upgraded my system last year. I tried a passive pre amp but removed it and now run the DAC direct to amp. The passive sounded fine but I ended up running it at full volume. No remote. I use the Bluesound ap to change volume. My thinking was less is better. My speakers are efficient and dynamic.

The Topping puts out 2V. Pass told me this is adequate. I am wondering what a preamp would do. How would it improve or degrade the sound? How much gain do I want from the preamp? Tube or solid state? Any other suggestions are welcome or should I just leave this alone? I don’t like buying, selling and failing. Here are some I saw that look interesting.

I would like to spend 2000 or less. I don’t need Phono. Remote volume would be nice. Thank you again.

Otherwise the passive vs active argument was going on in my mind.
Active preamps cannot make more dynamics than what’s on the music source to start with, if anything they can only reduce and add distortions/colouration. (they are not dynamic range expanders) thank god, as they are rubbish.

When a passive is matched into the system "they cannot" reduced dynamics or add distortion, it is the most transparent and dynamic way of getting the music source signal to the poweramp.

The only thing that’s better is direct connection to the poweramp, if the source has a digital domain volume control, and you go direct to poweramp, that’s used in the top 1/3 of full volume (otherwise below that it could "bit strip" if below 1/3 of full) if below then a $49 Schiit Sys passive can be used as volume preset so then the digital domain volume control can then be used in the top 1/3 of full volume.

@georgehifi   
active preamps can certainly add significant dynamics to the overall sound if a passive or inadequate active is not delivering what is on the recording.  
this is especially true for micro dynamics and quick transitions.  
haven't you ever heard this?  
similar to differences heard with various phono preamps.  the good ones deliver much more.

not always, but in my experience as a practical matter, more often than not, active pre’s do add to the sense of drive in a high quality, resolving system

Absolutely impossible for them to give more dynamics or detail than what’s from the source.!! unless they have a dbx inside, and as I said they sound crap.

They "can" add a colouration/distortion edge to the music making you "think" they are more dynamic.

Consider a EVS Ultimate attenuater. Do a google search for pics.Of course you will loose some dynamic range of a preamp, But can eliminate a set of cables ect, Works very nice. I have mine in use for a Bi-amp sitaution and use the EVS for level matching between amps, so its on my tube mono blocks with virtually no sound degrade.  .
