Is the D50s the best pairing for A50s amp?

As from the title,
I was waiting to see the price of the new a/d30 pro and they are too much for my budget so I decided to go for the A50s and I'm not sure if I should pair it with a D50s or something else. What do you think? I would like to spend less than 250eur for my DAC

If you do not need Bluetooth, The $150 Topping E30 will sound just as good, has most of the other features, and is just as compatible with the A50s. The E30 also looks fine stacked with the A50s. If you do not need the Optical/Coax inputs, the D10 will work fine too.
