Is MacBook Air 1.40 GHz, 128 GB SSD, 4 GB RAM enough as dedicated music source?

Hello!

I decided to use a separate Mac as a dedicated music source for my Devialet 120. A MacMini headless is
no option for me. Need a display and a keyboard/trackpad all-in-one! ;-)

Since a local dealer has a special offer @EUR 800,00 for a

>> MacBook Air 1.40 GHz, 128 GB SSD, 4 GB

I ask myself I this has sufficient power? Or are there some limitations?

1. Connection to Devialet should be ETH (via. Thunderbolt-Gigabit-Ehternet-Adapter) or USB
2. Music is stored on external HDD to be connected via USB3 to MacBook Air.

This model has Tunderbolt 1.0 with max 10 GBit/s. Is this suffienct for high res music?

What about processor speed and RAM with respect to other future players instead of or along with iTunes?

Thank you for advice!

Kind regards
