Weiss DAC501 vs Meitner MA1 V2

I am using currently Weiss DAc202.
As I have changed from MAC Mini to NUC Intel Windows10, I can't use my FireWire connections any more.
As I was happy with my DAC202 I am now considering upgrading to the 501. 
I have also heard positive comments on the MA1 V2 from Meitner  EMM.
Does anyone have any experience with
- 202 vs 501 and
- Weiss vs Meitner?
I am using an integrated amp from T+A PA3100HV and Sasha1.
Any comment is welcome!
