Most factories fond of using the kits of SONY.
1st generation IC combination: CX20108 RF AMP PLUS CX20109 SERVER AMP 
                                    like: SONY D50 D50MKII SANYO CP10 GRUNDIG CDP50
2rd generation IC combination: CXA1081 plus CXA1082
                                    like: SONY D100 D3 most table model made by various factories
3rd generation IC combination: CXA1271 plus CXA1272
                                    like: almost all vintage players made by SONY KENWOOD AIWA DENON except Toshiba
4th generation IC comnination: CXA1671 PLUS CXA1372
                                   like: mostly used by table model and CDROM
5th generation IC combination: CXA1782 (BUILT-IN RF AMP AND SERVER AMP)
                                  like: aiwa XP66/77
 
DSP: CXD23035 / 1125/ 1130 / 1135 / 1167 / 2500 /3027
 
DRIVER: always MPC1715 1716 or CXA1083, if player supports ESP, driver will use SC111280 which support double spindle speed.
 
Optical head: most players use kss220, it can directly replace KSS162/165/167, several models use SANYO SF89 head,like D303 350.
 
DAC: most players prefer to use NEC UPD6376, it appears in D101 202 33 350 even some technics' players. Personally I donnot like it evry much,especially when it combinates with BA3570，a little backgroud
noise, volume cannot shut down, bass muddle when turn on mega bass.
 
I prefer to use the DAC like PCM55 PCM67 made by B.B semiconductor, common players carry with
PCM55:
Technics sl-xp7
SONY D100 D50MKII
Philips CD10II
 
PCM67:
SONY D555 PCM66*2,
DENON DCP-100 PCM66*2
 
These players always be regarded as the top of the brand, they all have the balanced frequency, fine treble, they should be
the best choice of our Hi-Fi fans all. If you have the chance to compare your MP3 players and these vintage cd players, I think
these old fellows will gain revitalization in your hands.

Nice work! There are probably a few of these old CDPs floating around in Japan, so I might have to look out for the ones with the better DACs.

 

[andreu]

Nice work! I'm agree with you about the  PCM66 vs UPD6376. The BB dac sounds so much better than the NEC. The other day my standalone cd player just died and i was desperately looking for a temporary solution. So i just grabbed my 2 old sony discman d250 and d33 for a little listening through the line out to see which one should i choose. The result is that right now i'm listening the d250 and i'm amazed about how good it sounds. 
Now getting back to the DACs i'm curious about the NPC dac, the SM5871 used in "newer" units like D303 and D311. How does it compare to the older PCM66?

 

[kaosun]

Most people use earphone to listen to CDs, so the quality of the earphone amplifier should also be measured.
Both D303 D33 use BA3570 as earphone amplifier, so I have to say sorry to them.
However D250 uses CXD1316 as digital filter, PCM66 as DAC and M51568 as earphone amplifier, its overall quality is much higher than 303 and 33.
New components donot means high quality, maybe more cheaper.
D303 and 33 carry with DBB or MEGA BASS to boost its bass and treble, so maybe such sound will satisfy more common people, however it doesnot mean high sound quality.  

 

[Malefoda]

The D-303 in my hands feature a SM5861 DAC, not a SM5871 as listed. Was used in some Integra line of Onkyo wich are not that bad

Lucky 777th post!​

 

[kiteki]

I am blown away by the sound quality in my new KSS220 CXA1271 CXA1272 CXP5024 MPC1715 CXD1130/CXD1246 CXD1161 BA3570 MEGA BASS+M51568 !!
 
The line-out -> amp -> IEM's sounds very analog, warm, refined, panoramic... one of the best Hi-Fi experiences I've ever encountered - especially for a cheap second-hand CD player ...

If you have ever tried another better  portable cd player, even like D303 D25 D15, you will have another feeling about your D11.
D10 D555 will be more refine than D303 25 15 serial, D11/22 can only be regarded as entry level of vintage PCDP.

 

[kaosun]

SM5861/5871 should have same performance except some tiny difference between their working voltage or sth else.
The sound quality of D303 which carries SM5840 as DIGITAL FILLTER and SM5871 as DAC is not as good as the D100 which carries SM5804 as DIGITAL FILTER and PCM55 as DAC.
Bacause people always compare them with their earphones output, the quality of the earphone amp should be considered.
D303 uses BA3570 as earphones amp, while D100 uses NJM4560 operation amplifier with positive/negtive dual power supply to drive the 4560, it's more advanced than BA3570.
If you have chances, I suggest you to compare their sound quality only use their line out ports, it's a direct way to measure the quality of the DF and DAC.

anyone know what NPC oversampling chip was used on the Denon DCP-100? It is 8-times according to the brochure, not legended to the front of the player as it is on the DCP-150.

Oversampling chip is Sony CXD2551M
Line out amp is Mitsubishi 51568FP
2x PCM 66 DAC

two dead spiders inside and watch out for the ball bearings when you take off the toplid, they can take your eyes out!

 

[obsoletemachines]

this means audio (analog) wise the DCP-100 is identical to the Sony Z-555 Discman, viz

2x PCM66 and CXD2551 oversampling chip
