Amplifier tips

Just try to relax and set up your new speakers before you think of upgrading other things.  Evaluate your new speakers and see if you think anything is lacking. IMO, you should listen to any new item for at least 2 weeks minimum before making any decisions on what else to change.  And that is really a minimum.  Not to say your speakers shouldn't sound good after a few hours play, but it takes time for you as the listener to adapt to the new presentation before moving on. 

300 W rms minimum.
   U need the headroom, and reserve power.

  Even with high all speakers.

 My speakers are I think 92 db, I use 600W rms amplifier.

   Never clip, never a tweeter distorted sound, midrange always flawless, bass perfect.

I agree with @chayro  get the speakers and hook them up to your Mira. It should drive them reasonably well. Listen decide if you like the sound you're getting and go from there.

Thanks everyone for the reactions!!
Normally next Monday they should be at home to be listened to. I'm going to follow the given advice and let them(or me) acclimate a bit.
Great community!! 

Your totem staffs are rated at 88 dB efficiency and are 8 ohms for their impedance. The signature ones are rated at 87.5 DB efficiency, also into 8 ohms. Winner winner, chicken dinner!

If you're using the original Rega Mira, then you are putting 61 watts into that 8 ohm impedance. Regas tend to be more powerful than they are rated so you really shouldn't have any problem driving the signature ones. @chayro is right hook them up and see how they sound You're going to have to fiddle with placement and all that because you're going from a floor stander to a monitor, and if the signature ones are new then their sound is going to change as they burn in. So don't make an immediate judgment on the amplifier/speaker pairing based on your first, second or even 10th listen.
