Upsampling frequency adjustment in MHZS 88F player


I received the MHZS 88F CD player yesterday. The user manual is in Chinese, and I don't know how to change/select upsampling frequency. I tried to do it from remote but nothing seemed to happen. I will appreciate all recommendations.

Hi Transl
I recall the button to change upsampling on the top row of the remote marked 'kmz'sic. It had to be set before starting the cd.I used the highest sampling as it sounded best to me that way.It couldn't be changed while the player was playing a disc.
Since my 66e had no standby mode,I never turned it off. It took a day to get it to sound it's best when I turned it off.It only had two 12AX7's in my model,which,I was told would last for years even if I left it on.
Enjoy the music
Transl,
One more thing. You didn't mention if the player is new or not. If it is new, play it continuously for at least a week or more before you start to listen seriously to it. If you like it now it will sound better once broken in.

There is a write up and comparison of the MHZS and some other digital sources that may interest you plus some mod ideas towards the end of the article.

Hi Transl, did you ever contact Joe at Pac Valve? Don't know if he will send you an Eng manual or not. Not much to it really, tube rolling is straightforward. As mentioned, you can't change the upsampling while the disc is playing. Push the button while stopped and you should see the display cycle through the different bit rates.
