jaybe,
Yes, I would say the effects are similar. They both lower the noise floor, and work well together. I found the iQSEs work best when placed close to a power transformer. Inside the chassis, if possible/practical, but they still work well placed on the outside. I currently have 6 in my system. I added them one by one, and heard further improvements each time, so be prepared, if you go down that road 😉
