From my Lampizator dealer friend:
I had Atlantic in my system and is very good if seeking a little tube magic.
For 2017, Lampizator discontinued L4/L5/L6, and now have 3 DAC lines: Amber2 (better than L4 was), Atlantic (better than L5/L6 was) & Big7. There are different options & versions of each including top end Golden Atlantic and Golden Big7 is Golden Gate.
