Replace Parasound P6 & A21 combo with CARY Audio SI-300.2d

Looking for some advice - have a Parasound P6 / Halo A21 2 channel set up.  Paired with Focal 1028BE towers and a REL Ti9 sub.  I stream mostly Tidal with a Node 2i.
My tastes are a warmer amp / pre-amp.  I’ve never heard a Cary Audio product, learned about the company / brand on this forum.  What attracted me to the receiver / amp combo was it’s reference to trying to achieve “tune like sound” with a solid state Amp.  
I’ve gotten some advice from fellow hobbyists I trust that say the Cary will likely give me better sound, not due to the amp but the pre-amp section.  They have told me the A21 is bullet proof and hits way above its price point, I should look at a different pre-amp and keep the A21.  

Anyone have experience with Cary Audio or this particular unit?
