Thanks a lot. That mean my version is not optical input(only optical output) as of 4XL version that is no optical port at the back.

I think it’s came with optical input feature. I bought from Jaben in Singapore in 2014. But I never try that feature until now.

I play song from PC. So the optical cable come out from PC to the M8.

Thanks a lot for your advice. But it’s still not work. Please see pictures below for the set up.

For V1, when we plug optical cable to input 3.5mm plug ,then what’ switch signal selection I should use , go left , right or center. I try to select all positions but it’s not work, any advice?

Just found out that's caused from the quality of SD memory card.!

OK. Thanks for the thread link. I have put it there then.

I got my Zishan DSD AK4499 Nor version, and l used them for more than a week. In term of soud quality, it's amizing on its price. But I got a probem that the music albums/folders after 5th page did not show up the song list for all album. I have installed more than 80 album/folders on the micro...

Sorry, I forgot to ask the guy in the shop what's O2/ODAC(demo) gain during my audition. Anyway, to my ear M8 is more fun listening than O2.

My T1 is number 20124. I've done audition between O2/ODAC VS M8. To my ear, the M8 provide more power than O2/ODAC at the same volume position.

Thank you very much for your advice. I'll take a look for that.

For on the go set up, Could anyone recommend the portable amp+DAC that's a bit better sound quality than Entrance-Hifi M8 on the same price range?

Wow.! It's an awesome review comparison. Great done!! Helpful.! Thank you for the good ones to read.
