I was finally able to take a road trip and sit down with the 17LS2 for a few hours a month ago. I intended to buy one around Christmas because I loved my c-j DAC, but couldn't find anyone in the area that had one to audition.
I ended up buying a Herron VTSP-1A/166 from Karl Lozier (the reviewer) when he bought the new VTSP-2.
When I finally sat down with the 17LS2, I was never more happy with my decision to go with the Herron. In the current Absolute Sound, it's one of Harry P's "List" of five pre-amps, along with the c-j ART and ACT.
You might be really surprised if you'd give the Herron a listen.
