Look for a used ARC linestage preamp preferably their Reference series preamps such as the ARC Ref 6 or Ref 10 if you can afford them cause these ARC Ref 6 & Ref 10 preamps (especially the Ref 10 pre) cost many times more than the Mac C2600 preamp. Then get the ARC Reference series amps or you can still keep using your Rotel RB-1590 power amp for now and then upgrade to the ARC Reference series amps later down the road. ARC (Audio Research) gears pair really well with Wilson Audio speakers. McIntosh gears don’t sound good on Wilson Sasha speakers. McIntosh gears sounded good on Sonus Faber speakers though. Those are pretty good pairings.
The ARC Ref 6 or Ref 10 preamps will be a huge step up sonically from the McIntosh C2600 preamp. All ARC linestage preamps are pure analog linestage preamps (no DAC).
