Tube Preamp with Solid State Amp?

^^^ @ clearthink,
 to"dip a toe"in any waters is to start as small as $ possible with maximum gains..An inexpensive tube buffer would exhibit all the basics of how tubes affect the sound including true staging & instrument separation,depth of stage & tonal saturation...

I have been doing this since the 80's Conrad Johnson Premiere  2 with Adcom GFA 555. loved it. It really stepped up the dynamics of the Adcom. Audio Research LS2B with Krell KSA 100s. Softened up the Slam in your face of the Krell. Today still Audio Research LS 27 with ARC DS 450. CJ or ARC tube preamps work well with Your Parasound. 

I'm sort of at the opposite end. 
I have a solid state preamp and tube amp(s). I use multiples of subwoofers and I don't think tube preamps are up to that challenge.

I have a Luxman Cl38U SE w/a Bryston 2.5 SST2 powering a pair of Aerial 5T's. Gives me a nice detailed top end. Eliminates some of the harshness from streaming music.

I have a BLUESOUND Vault >MFA MAGUS A2 TUBE PREAMPLIFIER > MIetner MTR101 solid state  MONOBLOCKS > BOZAK URBAN Speakers; I got these used via Facebook Marketplace and was lucky to have experienced and friendly sellers and I was given good advice by them. I ended with this  setup that is fantastic! I want to add a higher end streamer DAC turntable but not until my budget allows and if it doesn’t allow I am fine as is.
