Overall, much quiter. I'll wring them out good this weekend. The installation was pretty straight forward. The ear seals that come with the kit, do not fit the DC 13.4. Fortunately I had ordered another set of gel seals, so I installed them. Thanks for everyones input!
I can't recall if I mentioned this before, but battery life varies a lot, depending on how much the system has to work. If I listen to music pretty much constantly, which I do on long cross countries when I don't need to listen to ATC all that much, battery life is much shorter. If it's just radio traffic, which even in busy areas isn't constant, it is longer. I've had it vary from as little as about 15-16 hours to as much as more than 25. Swapping batteries is relatively easy, but I keep a new battery under the battery case in the battery pouch, which I have Velcroed to the side panel of the airplane.
The other thing I can't recall mentioning, but if it shuts off because the battery is low, flipping the switch off and then back on will give you another 20-25 minutes of ANR. So like if you were in the middle of an approach, VFR or IFR, there would be plenty of time to complete the approach.
Fun keeping track of all those wires, right?

Thanks for tips Cary. I bought a costco pack of 9 volts and threw three of them in the glove box. The wiring was a bit out of control. The worst part was the small size and extra length. The install was pretty straight forward despite the several sets of un-organized and revised instructions that come with the kit. If you can read a picture book and have a good weller iron you're set!
I saw where Bose has some active ear muffs but the A20 sounded like it does a better job. Blue tooth for the phone might be handy.
