McIntosh MX150 and Non-McIntosh amps

Hi, any advices for non-McIntosh amps to use for surround speakers . For the front left and right speakers I have the McIntosh MC7300. I need an amplifier for one center and two surround speakers. I’m thinking about the NuPrime MCX-4 amp. thanks
Another solution would be to buy two Schitt Vidar

One used as a monoblock amplifier ( XLR connection ) for the front speaker 400W rms
One used as stereo amplifer ( RCA connection ) for the surround
speakers . 100W rms
Obiviously , I should have wrote ´´ center ´´ speaker rather than 
´´ front ´´ speaker , with the XLR connection ( as a monoblock)
I forgot to write that the amplifier must have 4 ohms option .
all my speakers have 4 ohms impedance .
