The C2200 and C2300 would offer better value than the C2600, and both aren’t burdened with the McIntosh DAC modules, which are easily bettered by external units of modest cost. A C2300 would come in under budget and allow for other system upgrades. Newer is not always better.
If you’re eager to spend your whole budget, than the C22 Mk V would get my vote. That will likely become collectors item in the future.
