Clayton2kI do not have this but I will say that if you are strictly looking to drive those headphones, you can also check out the Centrance DACport Slim which is currently available - https://www.massdrop.com/buy/centrance-dacport-slim-amp-dac-combo That has a very lengthy discussion thread so you may be able to get some answers outside of comparing the listed technical specs on both pages.
Clayton2kDid well enough with the 600's and 650's, as I comment on my after-drop review.
I like Senns better on tube amps, but they present well enough with the TP30.
If they re-drop this item, I hope my review will help.
