HELP! I bought equipment drunk, don’t know anything.

So I woke up with a very sore head and depleted bank account this morning.

Recently bought an Audiolab 6000a and Elekit TU-8500 tube preamp. I’ve never owned a preamp before and I hope they’re compatible for my KEF Q11.

I then had a few bottles of wine...

Woke up and saw I had purchased a passive pair of Bryston A2.

Will the amp be able to power the speakers? I don’t listen to loud music. 
Please help this idiot.
