Couple of impressions since I got my DR100 mkII back from Oade...
Turnaround time from Doug was pretty quick and Priority return shipping and insurance was included in the price of the mod - which was $185. ONLY the XLR inputs are upgraded. The internal mics go straight to the AD chip and it's integrated preamp and the miniplug line in uses a separate path too. Nothing is done to the digital signal path from the SPDIF input.
I gave this thing a workout this weekend at Jazzfest in New Orleans.
It has a nice, open, crisp sound that captures the low frequencies well but is nice and tight on the low end.
The decreased sensitivity took a little getting used to. Even in a ripping loud club only 25 feet away from the stacks I still ran it on medium gain (Low-Med-High switch) with the adjustment around 6-7 (10 is the highest). This was kind of a surprise. The gain structure is very much optimized for loud sources - more so than my Warm Mod UA5 even though it too has to be run with the gain pretty high even at loud shows.
It performed like a champ in the heat, the rain and in the bag at clubs. It's going to be my go to for 2 channel recordings.
The only hiccup was running it on Sunday at the Fairgrounds for Continental Drifters and the Radiators. I used a small 5V battery all weekend up to that point and didn't have any problems. I used my big Talentcell that day and both sets have a god awful staticky, electronic whining noise all over both recordings. It's bad enough to require major surgery but I think I can salvage them.
So it does not jive with all batteries - which is weird. EDIT - I may have spoken too soon. I did a test at home with 3 different batteries one of which was the one in use when the terrible interference happened and could not get the same result. Dead quiet with all 3 batteries. The interference had to be environmental. I was stack taping at the Gentilly stage at Jazzfest maybe 10 feet from the stack. Maybe there was some short of unshielded power supply close enough to create the interference.
