Chris (@Waltersalas), regarding your possible purchase of a Lyngdorf, before doing so I suggest that you contact the manufacturer and ask what the input impedances of its balanced and unbalanced analog inputs are. Those numbers appear to be unspecified for the 3400, while the 2170 has no spec for its unbalanced inputs but a very low 10K figure for its balanced input. Which in turn suggests the possibility that its unbalanced input impedance **might** be only 5K, and if so it would most likely not be a good match for your Allnic H1201 phono stage (1.2K nominal output impedance), and perhaps also for your tube-based Lampizator Atlantic DAC (for which output impedance appears to be unspecified).
