Hi Paul,
Strictly personal opinion based on owning back in the day both the D70MKII and the following ARC preamps:
SP-8: later versions, would be first choice
SP-9: MKII or MKIII, would be second choice
Although I have not owned one, I have heard the SP-6E many times as well, always with excellent results.
Good luck!
