I really enjoy the Freya S. I find the Nexus mode has a really great sound and has a flavor of it's own. I truly enjoy the preamp. The Freya S is a piece of kit that'll outlive whatever changes in gear around it due to how useful and compatible it is. I passed on the tubes in the + version and the Freya S can be had for $500ish used - no brainer! Plus it runs cool (The + runs very hot). I use it to convert BAL to SE for my RCA only power amp and another set of SE from the "S" is going to two powered woofers. I'm also able to test different DACs and setups (SE vs BAL, etc) really easy. Awesome piece of gear. My Freya+ only runs warm and only if using the tube buffer.
