Was checking out the specs for both players. I think both will be fine but I give the edge to the Q1 as it has a output impedance of less than 0.2 Ohms which is excellent for sensitive monitors. Plus Shanling likes to tune with a bit of warmth to their tunings which is a bit more musical in approach to tuning vs Fiios more neutral approach. Fiio M3K looks like it also has a low noise floor. But in this case I am willing to bet the Shanling will match up better with the Aladdin.

I value 'value' very highly, so I am sure I should be happy with the purchase.
In regards to the source.. I have a iAudio7 which is 12 odd years old.
Would you suggest FiiO M3K or Shanling - Q1 as source ?
