SLP-05 and MC-275

Thank you. I’m thinking to keep my current setup. I like it.

i have heard that MAC amp on a few occasions and never liked what I heard.  
I do have the Cary SLP 05 and love the sound driving my Parasound a21+ solid state amp with Harbeth speakers.  the combo does it all, tube warmth yet excellent transparency, dynamics, big 3d sound stage, high end refinement and you never run out of power.  
never heard the Cary but i see them used fairly regularily.  
another amp i can recommend over the Mac is the Rogue Audio Stereo 100 KT120 based.  Super clear, powerful and dynamic.  
Aslo consider the Benchmark AHB2 or possibly dual mono AHB2s.  well regarded sound quality.  

And maybe you should consider upgrading your source whatever that may be.
