I can’t comment on your possible choices but add that I’ve heard the Holo May and Cord Hugo TT, I was not overwhelmed. I demoed the new Aqua LaScala DAC and loved it. A friend of mine dropped over a Lumin U1 mini for kicks and I was surprised how good it was over my 1k streamer. I liked the Lumin sound so much I’ve purchased the U2 Lumin which will arrive in a week. At the end of the day, there was a comment made earlier that may help direct you. given what you currently have what would you like to have more off? Detail, warmth, sound stage, weight, etc. each component has its own signature and strength. In my experience and system the Aqua LaScala and Lumin combo provides all the above. The U2 should provide even more given the reviews I’ve seen. I can provide an update on the U2 in a few weeks.
