Some users are disappointed about the CDs writing quality of the A4 series.
After the improvements of the A1 series (thanks to Wind and edwin12355 :flower:), I've checked the situation of the A4 series through a DH-20A4H that I've bought for one friend of mine.
I've burned all discs at 16x, that is the lower speed available, because I think it's the preferred speed for audio CDs. In case of problems I've burned another disc at 48x, to see the difference, and another one with my DH-20A3H. I've many friends that choose the lower speed available to burn their audio CDs (also 4x or 8x) because they believe jitter is the lowest. Sometimes this is not true because writing strategies are better optimized at high speed.
In this cases the result is that the disc not play in the home/car cd player (see this thread).
I'm very happy of the CDs writing quality of my DH-20A3H. I think it's the best LiteOn CDs (DVDs) burner of all.
The first disc I've burned is a FUJIFILM 52x (Plasmon) @ 16x
No problem here.
