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!
The ARC SP8 is an all tube preamp (8 tubes total). The SP9 and SP14 were hybrids (2 tubes for SP9, 1 for SP14).

I have owned all of these and really preferred the SP9 and SP14 to the SP8.

IMHO, the SP9MKII or SP9MKIII are excellent choices. Tube rolling is also very inexpensive and easy with these preamps.
.
I have owned five different AR preamps....., and I loved them all except the SP9 Mkiii. It was too thin sounding and totally lacked guts and body compared to the others... I sold it after owning it for only a week.

.... Other AR preamps that I have owned

LS 10, Ref 1, Ref 2 mk2 and Ref 3
