My player is a Pioneer DV-355 Thanks I'll sing along with the chorus -- why do you need to replace the power supply? This does not sound like a good idea to me. ----------------------------------------------------------- spam: wordgame:123(abc):14 9 20 5 2 9 18 4 at 22 15 9 3 5 14 5 20 dot 3 15 13 (Barry Mann) [sorry about the puzzle, spammers are ruining my mailbox] ----------------------------------------------------------- |

If the power supply has a good clean DC output to operate your player, it
should not need servicing or substitution. There are many articles written in various magazines that indicate modifications, and claiming improvements in various equipment. The bottom line is that proper testing, comparisons, and evaluation are required to prove if these mods really work. -- JANA _____ "A S Goh" wrote in message ...

Hi All
Thanks for the respond In mod, people replace with better caps to get better sound. Switching PS is cheap and inferior when compared to normal PS with trans, that is what I understand. People mod Marantz 63 to improve the sound. There is nothing wrong with my player. Just trying to make it sound like a audiophile equipment. There are shops doing mod on this player. One shop in Malaysia call Octave. I am trying to DIY "TimPerry" wrote in message ... "A S Goh" wrote in message ... Hi rat How can I improve the switching power supply of a cd player?

Thanks for the respond In mod, people replace with better caps We are talking about the POWER SUPPLY, right? And a switching supply at that. Do these people know that switching supplies require special low-ESR capacitors in order to operate safely and properly? to get better sound. Only in their imaginations. A properly filtered power supply will be as stable and clean as a big battery and will have no effect, positive or negative on "the sound". Switching PS is cheap and inferior when compared to normal PS with trans, that is what I understand. You have been hanging around with those people your parents/parole officer warned you about. A great many pieces of equipment (likely including the equipment used to record the music you are playing back) uses switchmode power supplies. "Normal" linear PS are becoming as extinct as black vinyl LP records. People mod Marantz 63 to improve the sound. There is nothing wrong with my player. Just trying to make it sound like a audiophile equipment. Spend your money where it counts. The single most likely place you will hear an improvement from more investment is your speakers. There are shops doing mod on this player. One shop in Malaysia call Octave. I am trying to DIY Recommend becoming a shop yourself and bilking others out of their money. Then use your riches to buy good speakers for yourself. |

: In mod, people replace with better caps to get better sound. Switching PS is cheap and inferior when compared to normal PS with trans, that is what I understand. You understand incorrectly. A power supply isn't inferior if it does its intended job correctly. People mod Marantz 63 to improve the sound. Hoo boy -- you have been hanging out with the lunatic fringe. These are the same people that insist the sound is improved by special bricks to place on/under your CD player, wooden replacement knobs to control "bad vibrations", and special clocks to "condition" your power supply. That type of audiophile subscribes to pseudo-science at its worst. There is nothing wrong with my player. Just trying to make it sound like a audiophile equipment. Then just lie and tell your audiophile buddies that you already had it done. They will hear the improvement (try this if you don't believe me). There are shops doing mod on this player. One shop in Malaysia call Octave. I am trying to DIY If you want real "audiophile sound", then look at getting better speakers and/or improving the acoustics in your listening room. Your CD player isn't the problem. |

How can I improve the switching power supply of a cd player? Is it possible to replace with a normal power supply? My player is a Pioneer DV-355 Thanks Modding an SMPS is not a trivial task -- the ESR of the output filter capacitors affect the stability of the feedback (error control) loop -- you can make a decent supply awful if you use caps with a different ESR from those originally specified. |
