Marantz CD63 & CD67 mods list - Page 983

Malefoda · 27th April 2008, 10:54 AM

I have a flea in my CDP and that was cheap coz the PCB was cheap (even less than that!) and parts not too expensive. I was just looking for some cheap clock to mod a CDP and resell it... but time and money spend on it is not worth the money earned...
It's just a very big money saved in my own CDP =)

Does your flea use the stock oscilator ?

It uses the Tent Labs TCXO, as standard Flea's design.

Do you know what is inside the XO module ?

Hi Ray,

I had an old Marantz professional recorder/player unit with its "remote control" : the CDR 620. I upgraded the firmware years ago... I suppose there are several other Marantz units which are similar to this one. Do you know which one ? Otherwise what can be done to improve its audio quality ?

When compared to my MacBook Pro the same CD sounded poorly with the Marantz even when using only digital connections like the AES-EBU output...
Of course the analog is far from to be usable !

Thank you for your advice in this tweaking,

OndesX

No, i'm sorry, I don't know that model from the inside. But The General Rules of Tweaking can be applied to make it sound better: improve the power supply, change the opamps, improve the analog filter, insert a decent clock...

But first i'd recommend you take a look and see if you can find out what type of DAC this unit uses. If it's old, as you say, it might not be worth the trouble because the gains won't be that big. But every unit can be made to sound better with a few tweaks; it depends on the design what the level of quality will be in the end.

Regards,

Ray

Can anybody share a little tech info ?

I must understand the difference between the various clocks before I have a go with any of them.

Hope some of you will help as usual

Regards
