op
here are a number of solid state amps (some integrated) i think would work GREAT with vandy 2ce sigs, are commensurate with the level of that speaker, and cost effective too (compared to 6 grand for the arc amp)

these will all give you great sound with your speakers and will match very well in tone, and ability to drive them properly, esp on the bass end -- at these prices, you can enjoy, and resell at minimal loss if they don’t suit your fancy (i have zero affiliation with any of these, do your due diligence on seller and condition)
that said, if you like tubes, prefer eye candy to sonic/system synergy with the 2ce’s, and/or plan to move onto better more expensive speakers, by all means the arc ref75 is an absolutely wonderful amp to own
