There are 2 DC-100o's listed on the Canuck site - one in Ottawa and one in BC. The BC listing shows a more realistic retail price - but it is 2K above the 2024 list price (which is the last year Canadian dealers could post Accuphase retail prices. The reason is that we pay say C27K for the same unit that retails for US27K in the US - there is a big discrepancy between US and Canadian list prices).
The Ottawa listing has an inflated retail price but the asking price is decent - but as a dealer I think he has to charge HST.
The DC-1000 has the same list price as the C-2900, and the DP-770 is within 1K. The DC-1000 is a much more sophisticated DAC than the DP-770 - it is not just a DP-770 minus the transport. Look at them 'under the hood' on the Accuphse website.
Accuphase makes excellent phono-pre amps. I have a C-47 which replaced the AD-2900 phono unit in my C-2900 which is an available option. The AD-2900 is a much bigger and more substantial unit than the slim AD-60 phono card that fits into the C-2300.
I have an Accuphase E-380 integrated amp in a second system and I put a DAC-60 card in it and it is surprisingly decent sounding.
