I decided to try the Lampizator v3 Level 3. I will also be auditioning the APL DAC-S in a couple weeks. Alex is very convincing. I am intrigued that the DAC-S offers much of what the NWO player does, similarly to how the Reimyo-DAP delivered most of what their CDP did.
With regards to Tron Seven DAC, I'm told to forget it with my $4K max budget. An updated version is about to be released and the price has gone up.
