i believe audio research makes a tube dac as well as amr. i am not sure of the model names.
regarding the zanden. i prefer the original zanden to the later versions. i find the original version more full bodied and more in keeping with the classic tube sound, but not to the extent of sounding syrupy , veiled or a significant loss of resolution.
