I missed the massdrop, thinking too much and hesitating with a used Teac UD-H501 wich is still more expensive (roughly $120 more). Adding cross atlantic postage made it a not so huge deal also.
For a USB only source to listen with an integrated amp (unbalanced RCA input) would you think ? Everyone seems to agree the M8A performs well once you give it a decent powersupply, the SMSL P-1 is another €140 added, that would put them at the same costs. I was thinking the Teac may probably resale easier on the next time I will want to upgrade
