I paired this with the ClearAmp and it's like night and day! Clean and crisp audio are a must. The NGPC is already a very quiet system and I didn't play it much because I could barely hear it most of the time. Super easy install as well.

I got two of each (CleanAmp Pro & Dehum/Dehiss) for my NGPC & NGPC Slim. The difference in sound quality, clarity & especially volume was night and day! I've used these kits before on Nintendo handhelds and the gains were worth it but modest - but for the NGPC it is a HUGE improvement over stock! Not only is the sound better overall but now even headphones are amazing (used to hate using headphones before since the quality was marginal at best and bad buzzing and hissing was constant). Installation was easy. 2 solder points for the speaker, 6 solder points for the amp & 3 solder points for the dehum - one of which is shared with one of the 6 points on the CleanAmp so really only 10 quick dabs of solder in total. Since it's wire free the actual positioning and soldering itself took 2-3 minutes!! 90% of my time was opening up the handheld and putting it back together afterwards. Soldering into the NGPC Slim was more work but that's because it wasn't designed for it, but RetroSix was kind enough to give me a photo showing how to install it in the Slim model with a few bits of wire. I couldn't be happier with the results!

(This review will be cross-posted on both the CleanAmp Pro and Dehum/Dehiss pages. I highly recommend you buy BOTH for the best possible results!)

Using this with an amplifier and IPS, and all is quiet. Easy install too.

Bought it with pro amp awesome
