I use a pair of CineMag CMQEE-3440A step ups with my DL103. I think that these are used in some of Bob's Devices SUTs. There is an in depth wright up over at The Analog Department on the DL103 and CMQEE-3440A. Look in the Articles and Reviews section. I think that it is an article titled "MC step up devices part 1" or something along that line.
