Amplifier tips

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.


my .oo2¢

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.

Good feedback here - listen first, My experience with the Totem Ones, which has been a while, was that notwithstanding their specs, they did seem to want more power than the numbers would suggest. They came alive with amps that could swing a bit of power, and I don’t have experience with the Rega to know what it can do. With lower power they sounded fine but when pushed they felt a bit compressed and flat, and the top end had a bit more hardness. 
I do remember they had great imaging and soundstage.
