Amplifier suggestion for Dynaudio Sapphire

Hi,

I bought a pair of Dynaudio Sapphire speakers. My electronics and cables are;

Classe Cap-2100
Ear Acute cd player
Pro-ject Extension(with ortfon Jubilee)
Unison Phono One Phone Pre
Auidoquest Volcano speaker cable, Sky Analog interconnects.

I do not have a budget limit to buy electronics(also no rush) but I do not want to spend my money for uncessary ultra expensive equipment. I am considering EAR 890 power&868 pre, ASR Emitter I with battery, Audio Research REF3(2nd hand of course)+REF110, Musical Fidelity AMS series vs. vs.
