Obscure Chinese DAPs

First measurements without load and at 32 Ohms. As usual with xDuoo specifications, they are exaggerated. On the other hand, a voltage of almost 1.2V in such a small device, I find almost excellent.
Also, the output impedance is very low, less than 1.
Such values are not easy to find at this price.

Power at 33 Ohms = 41.48mW
Power at 16 Ohms = 85mW

I can't deny that I'm delighted with this thing.

battle of a bunch of chifi unknowns this morning
so far listening with the TC-200
the Nuansa, Xduoo, and Fiwwat have been sounded the best
the MF-01 has some depth/punch but feels boomy
the xDuoo has the best form factor (just received last night from china hence the comparison this morning)
The Nuansa P1 probably shouldn't be in the lineup being prived at $350 USD
will try them later with the starfield and modded kph30i

sorry about the wobbly photos need a better phone camera than my blackberry

While searching for an entry-level mini DAP, but one to have MSEB and other magical features, I found the R2 from HiBy Music !

It has an excellent GUI, really ergonomic shape, and a decent driving power too. For the price of 100 USD, it is one of the most complete DAPs you can get for jogging, or if you simply want something tiny.

Hiby ensures a good OS stability, and I can say I had fun reviewing it. I invite you to read my full article, and if you have questions, I am around to help ~ :)

The high end version is mostly is special edition limited to100 units with better build quality, serial number from 001-100, golden color and HDAM2627 instead of HDAM9988.
