Tube Preamp with Solid State Amp?

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. 

I'm also searching but I also need XLR inputs on a tubed line stage/preamp as my Nagra MPA has only XLR's.

Atma-Sphere, BAT, Aesthetix...

Love my combination of Parasound A21 + Backert Labs Rhumba 1.3 which is a tube preamp. The resolution, soundstage width/depth and impacts are stunning!

I been running a tube pre (mullards) and a class D PS audio amp for years.  Has a great sweet spot at moderate levels but the punch can be fatiguing at higher levels.  Been considering trying a class A/B power. Love how cool the Class D runs.

That's exactly how I set up my system and I like it. I was doing so much streaming that I thought a tube preamp would add the right dimension and it has. I read about the Prima Luna Dialogue for a few years and finally added it to a pair of SS amps. The result is great. Only drawback is you can leave the SS amps on all the time but you have to switch them off when you turn on the tube preamp but that's the only drawback I've experienced over the years.
