Amplifier tips

Hey community. It’s the first time I participate in audio discussions online so I will dive straight into it. I’m the owner of a pair of totem staffs with a rega mira amplifier. In a couple of weeks I’m getting an upgrade in the form of a pair of signature Ones. Does anybody knows if my amp can handle these speakers or maybe has some advise on other amplifiers that would pair well. My budget is around €2000.
I was looking at the technics su 700 or maybe something like the hegels. A big part of music would be played from my pc so a reasonable dac is maybe a must. Any input would be very welcome.
Thx in advance.
