To rja: Yes, it is getting good reviews.
To: tvad: I spoke to Lampizator today and was given some interesting information. First, the Amber 4 is a solid upgrade from the Amber 3. Second, the Baltic 3 is in the middle of an important upgrade. A quote from today: "Although we kept the Baltic 3 name, as of October all Baltic 3s ship with our newest engine 11. Same engine that will be going into our Golden Gate 3 as well. I was using an Amber 4 but just got the newest Baltic 3 and it's a very nice upgrade. Like the old B3 it's more resolved from top to bottom. The added improvement is a much more liquid presentation now. Again, great DACs getting upgrades.
