I bet if you measure the power adapter's output, it will be close to 9v like mine was.
Same here. Zero noise, no thumps, and amazing sound that surpasses HU for quality when playing a good source, such as FLAC instead of 192k mp3. Now for ease of setup, the HU wins no contest. But that's the fun part anyway.Not only did the crackle go away, I no longer have that annoying turn on pop that I could never get rid of (tried everything), I no longer have engine/electrical whine noise (or any noticeable noise for that matter). My gains are set back to normal (not cranked up to get sound) and the SQ is amazing.
