Musiland 02 is a DAC good enough for general listening. However, with a better amp, it is easy to find DACs that can better match your better amp.
On the other hand, I find that Musilnd 01 USD does an excellent job to read digital info from my computer. I am very happy to use it with my heavily modified DACs. I feel that Musilnd 02 can also perform comparably well for outputting digital info. One way to take advantage of this property is to use the Musiland 02 with your amp for now, then use the Musiland 02 with a better DAC and your amp.
I am using a Musiland 02 with a Little Dot MKV in my office and I am satisfied with this configuration. But at home, I am using a Musiland 01 USD with a choice of a DAC and am amp for more involving listening.
