Bought to compliment my existing IG3T pair; the new versions now have the Rednet handles incorporated so no need to purchase separately. There has been a firmware upgrade for this version where the tunings sound slightly sweeter and true to the original recordings. Build quality is as expected with Db Technologies (Very good), solid with a rich feature set to match. Also bought another pair of the Db covers; again, quality is superb.
I also own 4 IG2T as well; the 4 stack (2 either side) column array sounds fantastic!
