I’m doing it because I am a bass head. (BHK Pre-First Watt J2)I find the low end has more punch and slam with a SS amp. Adding a tube pre adds a touch of silk to the mids and highs.
One thing to consider (I have Zu Omen defs 101 db), is if you have too much gain in your system, tube hiss and noise will be much more prominent with super efficient speakers. My total gain (pre and amp) is around 33 db (using balanced connections). I did have a high gain amp (StA200) that made my total gain around 43db (single ended) and it was hiss city. I had to place a passive volume control between the pre and amp.
I thought some Parasound amps have gain control which would be quite helpful if experimenting with a tube pre.
One thing you may want to consider is a tube buffer. I’m not certain if a buffer would help or just be a noise maker. I’m sure many here on AG will have experience. Decware makes one https://www.decware.com/newsite/zbox.htm
