Hello to everyone !
Has anyone have any experience with the MHZS 33E cd player ?
First things fist the DA chip in that player does not look like a chip , there are no pins . Is this a fake chip all together ?
If the chip is fake how can the adjustable 44.1 to 96. be done? Is that all bull or what ? Then how does it convert D to A anyway ?
Number 2, does anyone have any Idea what opamps sound best in the
Unit, rt now there are BB 2604 , and tried LF 353N . To me the 353N had more bass but less clarity !
Is this player a fraud ??

Hi,
It is the little brother of the players covered by Lukasz here:

You mean this?

Non at all. The DAC Chip is the same as in that famous 60 USD Toshiba DVD Player that was all the rage to mod a few years back.
The consensus was the sound was best straight from the DAC Chip via a single coupling Capacitor. I used earlier version of this chip (very little but some convenience features and the model number have changed since), the PCM1716 and can confirm this.
There is also a Vref or some such pin with a Capacitor on it (either one or one per channel - I'd have to check the datasheet), this is actually a "hidden" coupling capacitor (hidden unless you know what's inside the chip) and getting this right makes a huge difference, as does a good powersupply.
All that said, at it's best I found the sound quality from PCM1716 rather uninspiring and I have no reason to think the later versions materially improved.
You decide.
Ciao T

I was just mean, sorry. I don't want to say that YOU should ask the money back, that's what I would do. Just to teach them a lesson in being truthful to their clients and not think that they are "stupid americans with money to spend".
Now... It is normal to hear something without the filter OpAmp in place since the signal (voltage output of the DAC) can go via the feedback network to the output. It won't be a nice sound, but it will be, especially if the next stage has a high input impedance (tubes).

Thats ok , I bout it used ! If played with nothing in it would that give a sound with no character ? With the next stage meaning the amp ? It is a tube also !!
