Hi Ed,
I bought the G6H Beta version directly in China and as far as I remember I paid around 1500RMB, but it is a Beta version and looks hand soldered. As I described earlier it is working very well and the sound quality is comparable to the TI evaluation board. I use a Mean Well RSP-1000-48 as a PSU for the TI board with disconnected fans.

We admire the meticulous engineers like you, this is the Chinese Government has strongly advocated the spirit of craftsman, we will continue to work hard, and strive to make our products better.
4channel TPA3255 professional audio amplifier.
2 channel of G6H amplifier has through test, and will apply in our customer professional products , currently we now planto design 4 channel of TPA3255 amplifier,due to TPA3255 has excellent of low frequency performance, we will use 4 pcs TPA3255 chip, each chip independent run in PBTL mode, to improve signal of channel isolation .
For professional occasions using, we plan to integrated DSP unit, strengthened EQ/LIMITER/NOISE GATE function, improves the reliability of various applications, I hope everyone with more valuable comments.

sorry for the convenience , all the AP test results provide to customers only, it is customer order module.
we will make some common module with TPA3255， we will list AP test results here at that ime.

Hello,Kaffimann
so long time in business, few time to discuss the technology here,very busy now, our products have widely used in industry, especialy in high railway system.
G36 and other DSP products have not update now,this product belongs to the minority products, it is difficult to achieve the ultimate.
we will make it later version if we have time, thank you for your supports!
