@milpai Sounds good re your volume control! As you realize, in contrast to many resistive-based controls a TVC will do well at low volume settings. The main concern, and I suspect the only concern, would be running out of range when you may want to listen at particularly low levels, and it sounds like that wouldn't happen with your system even with the very high sensitivity of the DI.
Regarding your other question, no, I'm sufficiently happy with my Daedalus Ulysses that I don't envision trying any other speakers in the foreseeable future. See my post in this thread dated 6-10-2017. But I find it interesting to follow and occasionally contribute to the thread. And of course the comparison Chris (Waltersalas) is performing and reporting on between the DI and the Ulysses is especially interesting, as he uses or has used the same speakers, amplifier, phono stage, and phono cartridge as I do.
