Selling my 2017 version Audio-GD master 9. I'm the original owner.

I asked Kingwa to customize this amp to have two 4-pin XLR output jacks and two 6.35mm output jacks. Because 3 pin XLR output is so rarely used and an extra 4-pin XLR output and a 6.35 mm output will be much more useful while comparing headphones. I think it was the right decision because now the new Master 9P has the same configuration.

I have been using this amp for 3+ years. Except it's size and plain design, I like everything about it.

This amp is powerful, neutral(slightly warm), resolving, smooth and transparent with absolutely no harshness sound.

It pairs great with most of my headphones (T1, DT880, DT990, HD800s, HD6XX, TH900PW and D9200) not very well with the Grado GH2.

I had 3 DACs since I bought this amp: Chord Qutest, Matrix XSP and Singxer SDA6. Master 9 always reflect the changes and improvement of the system very well.It is a reference amp that I never see any issue caused by it.

I am moving to a new place in September, I probably won't have enough space to keep it, that's why I put it up here for sale.

The amp is fully functional, clean and in good condition and come with the original packaging and accessories(remote and power cord). There are a few scratches on the volume nob, I showed them in the pictures.
