Tobes,
When we did the direct comparison between the Choir Audio SUT-H (HM-3) vs. Bob's Cinemag Blue unit, I had the SUT-H set at 7-40 Ohms (+26dB). Bob's Cinemag 3440AH SUT was set to 1:16 (+24dB). But as I recall, we tried both units both ways, and the above loading sounded best.
To be fair, I should note that I had originally purchased the Choir SUT-H for use with a modded Denon DL-103R cartridge. With that cartridge the two units are closer; although I still find that the Cinemag Blue unit is more detailed and sweet sounding. The HM-3 sounds more warm, fat and "wet". With the Benz or my Ortofon cartridges I prefer the detail I hear with the Cinemag Blue SUT.
