Hi interest buyers and collectors,

First, i am new to stereo2go so i wanted to take this opportunity to reach people here in these website since its only fair to reach more people globaly. Well, i want you to know that my goal is accurately describe an item with all sincerity. I have a Sony discman which is considered the "King of all discmans" from peers, forums, and research. I think i have a discman that everyone wants and desire to have in there hands or in there collection. Everything including box is in excellent condition. In addition, its 'Brand New' Sony Discman D555 along with proof of purchase receipt in early 1990's from authorize dealer.

I know you all understand that finding this player in working condition and with box in good condition is well. Please look at the pictures. It is rare to find one of these maybe a year or more on ebay and thats optimistic. This is a opportunity for someone to own certainly one of the MOST DESIRABLE AND BEYOND TECHNOLOGY AND INNOVATION walkman ever made by Sony.  PM me with "reasonable" offers.  If you are paying in GBP or EURO you are buying in USD at a HUGE BARGAIN.   Please make offers in "YOUR" currency.

The D-555 was the first Discman to employ 8 times oversampling. This method of CD playback reduced the amount of digital “noise” that could enter the analogue stages and resulted in a purer sound than was obtainable by conventional means. Sony’s own CXD2551 digital filter was used, feeding two Burr Brown PCM66P digital to analogue converter (DAC) chips. This arrangement would have been a high specification for a domestic machine but in applying it to a Discman Sony demonstrated how serious they were about portable audio. On top of this, they also included one of the first “Digital Signal Processors” (DSP) to be seen in a consumer product. The functions of the DSP were shown on an extra LCD on top of the machine and included a programmable 5 band graphic equaliser, digital surround sound and various other enhancement options. The volume control was also implemented digitally and this had its own display section too. On normal playback the DSP displays became a peak programme meter and both the DSP display on the top and the track display on the front were illuminated in orange when an external power source was used.

The D-555 was also unique at the time in offering an optical digital output. This could be used to connect the player to an external DAC, a digital amplifier, a Digital Audio Tape (DAT) recorder or later a MiniDisc recorder like the MZ-1. Text copyright © Walkman Central. Unauthorised reproduction prohibited.The D-555 was produced at a time when the personal compact disc player was still considered a luxury item. The situation would change in the next few years and soon such machines would be reduced to the status of a more common commodity. This precluded the production of further extravagant technology statements like the D-Z555, it is most unlikely that their like will be seen again.

Please email me for further information and or pictures.

Sincerely,

Indeed a nice unit.  I was watching one of these a couple of weeks ago, it went for £56 in the end which was beyond my means.

Also, I trust you're aware of copyright laws?  I mention this because the owner of Walkman Central is a member here.

56..???

you should have bought that one.

it's not the best sony= sound quality, but one of the most beautiful sony.

a real 80's gem

I owned one with the optional battery pack  and a pair of CD-7's in the early 90's. I really regret selling it now.

Is the Sony D555 discman still for sale? If so,can you please contact me jskills414@aol.com.

Is this D-555 still available?  Thanks

A collectors dream certainly to find this model basically NIB complete.  I have seen over past 18 months working players with some accessories go for $300-500 USD.    Although I hear that often when you boost bass the circuits over time something goes wrong.  Hugo has one and someone else I think with same problem.   You should certainly play the unit and check all functions work correctly as time is an enemy of these seems even more than use.   IMO it is one of the most desirable PCDP's ever made.  Good luck and welcome to the forum.

Definitely! The Z-555 is a must have Discman. I have one boxed that I bought partially working (the output was very low and only one channel) but managed to repair it. Now is working perfectly, except the problem of the strange bass EQ as you said, John.

@Vintagetogo: As Agent Orange said, to copy and paste copyrighted text is not a good thing. You even copied that: "Text copyright © Walkman Central. Unauthorised reproduction prohibited.".

For these cases is much better to simply insert a link to the original webpage.

You may correct your post and delete that part.

The D-Z555 one of my favorites CDP's. Had to replaced every surface mount capacitors, now works correctly.

How much are you selling the Sony D-555 for?

Hi Hugo,

May I ask whether are you replacing the capacitors to address the faint output on your unit? Because I have the similar problem of low audio output to headphone as well.

It cause by bad headphone output coupling caps, You have to replace 3 bad 6.3v 100uf, 6.3mm width 5.7mm height, SMD electrolytic capacitors. two in the headphone amp stage, one in the powersupply. Use Nichicon 220uf, 16v as replacements for the 2 coupling caps in the headphone amp stage.  It's a common problem with this model, fix a few of them with this issue.

Thanks a lot , Retrodos.

By the way, I have another discman trying to replace bad caps. I tried using alternative types of electrolytic as below by soldered on top of the board with those leads shortened ..

..instead of this original type (shown below ) but it wouldn't work, no sound from the output. Don't see why it doesn't work perhaps you can help to explain.

Could be broken traces, when capacitors leak the electrolytic,  corrosion can occur eating the trace up, Could be whole another issue like power regulator has failed, which I also seen, or bad opamp. Would check the traces first.

Hi Retrodos, thanks again for the advice. I will continue to diagnose the problem as suggested.

Well, I didn't repair it; it was a qualified technician here. I remember he told me he changed (I'm not sure) some capacitors and some other component...

But retrodos is giving you more detailed info.

How much would you sell it for?

My email is darmawaa@bdg.centrin.net.id

Hi, my name is Ryan and I just found these forums by searching for the D-Z555 because I've inherited one (along with a LOT of other Sony MD equipment) from my late father, who worked for both Sony and Bose.

I have a WORKING D-Z555 that I'm trying to sell, as well as other MD walkman and standalone MD units.

Anyone here interested? 

I still have my Sony DZ555 CD Walkman! I haven't used it in 15years and parts have ceased up!

Whats the best way to get it going again?

Oh also I got the infrared remote control and the additional sensor that you plug into the headphone socket too!

The additional accessory was the remote control RM-DM1 and the sensor attachment RM-DM1K

it becomes a full complete Deck style CD player with optical output and also a Line-out for full experience!

mine is still "fully working" but it is very sensitive to vibration and needs a vibration obsorbing mat or base!
