Tube Preamp with Solid State Amp?


Greetings!

I’ve seen some folks using Tube Preamps with Solid State Am ps. I’m thinking of doing that with my system as part of an incremental change. I currently have a Parasound P5 preamp with a Parasound A21 driving Klipsch Cornwall 4’s. Will a decent / good Tube Preamp really make a difference in my sound? I enjoy what I have now but really want to experience Tubes in my system. Thanks!

People with high sensitivity speakers might be shocked by how good they can sound with a really good tube preamp like a Supratek driving a really cheap gainclone type chip amp.

I'm also searching but I also need XLR inputs on a tubed line stage/preamp as my Nagra MPA has only XLR's.
I don't want a transformer/adapter XLR-RCA.
  Any suggestions?
Speakers are Wilson Sabrinas, only digital source.
thx

I also have a Parasound A21 amp and I'm running a Jolida Fusion DAC preamp. It's a great combination. The soundstage is really lifelike. I'm running Meadowlark Kestrals. I got the factory upgrade option from Jolida.
I run digital music exclusively, either through Bluetooth or using my PC as a source over the USB cable.
I am running the balanced XLR connection between the two.
I am completely happy with this system.
