I own the above cd player and thinnking of making a few modifications to the standard spec these being changin the opamp and capacitors. Also the muting circuit is failing on my machine and it clicks between tracks Fidelity Audio have said they will bypass this also I am changing the fixed mains lead to an IEC connector so I can upgrade the mains cable what improvements should I see ?
Marantz CD63 ki modifying
- Thread starter lewis hurlin
- Start date
CD 63 KI is still a wonderful CDP even though it was first launched about 20 years ago. The stock CDP is good but cannot be regarded as a high ended machine unless you make a number of changes. I have modded two CD63 KI and I am using all the top of the range components costing me more than £700 in total (per CDP) not including the KI which was about £100. I can tell you the result is stunning and it can compete with any CDP in the range of £3000 and more. If you seek the assistance of third party modders it will cost you a fortune and I suggest you mod the CDP yourself. There are more than 2000 pages of threads in ww.diyaudio.com and you may wish to have a look at it.
Change the capacitors and the opamps is surely the first step to go but the improvements may not be very much. You need to fit two very low jitter clocks for the servo and the DAC/decoder with its low noise independent supplies. Put a number of very low noise regulators to eliminate all the noise in the DC rails supplying to various circuits. The most important of all is to change the stock transformer to very big ratings to ensure the voltage is extremely stable in particular the one for the servo. My last advise is to use high grade components and cheap capacitors and low grade clocks will not change your CD63 to a high ended machine.

I have spoken to redhill audio and getting mods done in the new year they will include a low jitter clock new opamps and capacitors along with upgrading the mains cable all seems to be a good price. Let you know. I may also get hom to upgrade my Audiolab 8000a after.
