Lampi Baltic is way at the bottom of the Lampi chain. Lampi has many models above it. Since you are shopping for dacs you should head to Dac thread or for Lampi differences to a Lampi thread.Is a Lampi Baltic 4 already seriously good or do you have to go ways further to get the quality right?
For Dac Vs server you can check what Taiko, Aurender, antipodes and innuos guys each think compared to the dacs and servers they changed.
This is a digital Vs vinyl thread so you are off topic
