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.

Thanks for the recommendations.  I am wondering about the difference in sound between the 12AU7, 6189W, 6SN7 vs 300B.  Bottlehead makes a preamp that uses a 300B which seems unique, but I am not a kit builder.  There are several choices in volume controls as well.  Is the main improvement more linear control or is there a better sound as well?

Don Sachs here.  I see above that someone mistakenly things the tubes4hifi preamps are somehow given to me for tweaking.  Huh?   I get the bare board from Roy.  He has changed the board over the years with suggestions I have made.   That is it.  I choose every part.  I run the tubes at a different operating point.   I have modded the power supply and filament supplies, I use a much shorter signal path, I run the tubes on top and out in the open.  I use a 6BY5 rectifier, etc...   You can buy an sp14 kit and love it.  You can have Roy build you one and you will love it.  But it won't be my preamp.

I apologize for that, Don.  I do not understand what it takes to build equipment and should be more careful when posting.

A DHT pre would use 300B tubes. Some like DHT tubes in a pre while others do not. I have heard DHT pre amps that give the illusion of being at the performance with a spooky realism. For this reason i have ordered the Supratek DHT/6SN7 pre amp it gives the ability to use 6SN7 or you can switch to a DHT tube the best of both worlds.
