I heard LOIT in the Zellaton showroom - extraordinary sound in this setup.
Best sound in Munich - LOIT was compared to a €50000 turntable, and LOIT sound was very close.
One could clearly hear that this was R2R ladder dac, delta sigma has different sound - difficult to explain the difference in words - but R2R sounds more "there", has more finesse, more analog like.
Delta sigma sounds whatever the brand - more machine like, more in the face sound - one must compare it side by side yourself - my favorite dac every time is R2R.
The display of LOIT was dark.
