I also own the Less is More YGGY and your assessment is right on!
Enjoy the new YGGY!
If you want to spend $3k or more and think it is a big improvement be my guest…you are wasting your money, IMO.
I have compared the top DACs on top of the line STAX headphones that are more revealing of quality then speakers.
Listening in your own home, long term, is better than listening through speakers, that may not be properly setup to your taste, in a store.
