First of all, I would like to state that the price difference between the two machines in this comparison is not large, so that the comparison will be more meaningful.
For videos of the actual test, please click directly on the link to listen: which is better to listen to the 1541 decoder or the Philips CD?
In addition, this comparison is only for the entertainment of the officials, do not like to spray.
Interested officials please continue to read down on some of the basic information of this comparison and some of my personal sharing of actual listening.
First, let's introduce the two protagonists:
Philips CD machine, model CD940/00S, was produced in 1993, 28 years ago
Philips CD 940/00S
The bald head adopts CDM-9/44 (not a replacement version of the bald CDM4)
INSIDE THE CD940
The CD player in my hand is old but still old, reading discs quickly, and burning discs can be read and played very quickly. The decoding chip uses a combination of SAA7350GP and SAA7310GP, Philips CD850 (used price of more than 3000 yuan) and CD850MK2 (used price of more than 5000 yuan) also use these two chips, which shows that the sound quality of this CD is guaranteed.

The overall condition of the machine is good, and if it is properly maintained, it should not be a problem to use it for several years. This also guarantees the basic requirements for the smooth conduct of the test.
TDA1541 decoder, the overall machine size of 19 * 21 * 6CM, weight of about 3KG, compared with the CD player is much smaller.

1541 decoder and CD comparison
This decoder is a DIY product, the internal workmanship is relatively regular, using two BILLION "cows", although not top-notch, but the performance is stable, the bottom noise is almost nothing. This decoder input part uses Philips' TDA1315H, the decoder chip uses a famous TDA1541A, and the op amp part uses BB's four OPA627AP.
Inside the decoder
Decoder test part, the front end must be the computer (JRVER for the player), and then connected the USB to a lezhibang 01 USD digital interface and then through the coaxial output of lezhibang to input the audio signal to the 1541 decoder, of course, you can also directly computer USB to 1541 decoder, but I think after adding the lezhibang digital interface, even if you do not open the DSP, the sound is better than the direct computer output to the 1541 decoder, less treble glitch, the human voice is thicker. In addition, the digital interface can also open the DSP effect, according to their own listening preferences to adjust the effect of high and low frequencies, the playability is very high, in addition, the key this small thing is now second-hand cheap (more than 100 yuan), very cost-effective.

These two machines are 16BIT decoding chips, if you look at the performance indicators of this type of chip has lagged behind a lot, but used to play lossless format (CD) of the music has been enough, although now a lot of DSD music than lossless music in the indicators are much higher, the actual sense of listening is indeed much better (based on the same price comparison), but after all, the real DSD or HERS file is still not as good as the CD, because many record companies only released the version of the CD, Therefore, the 16BIT chip machine can also exert some waste heat in the next period of time, after all, there are still many resources in lossless format.
The track I chose for this comparison is Dolma's "Paradise Prairie", the CD was purchased from Xinhua Bookstore (absolutely genuine), and the decoder played the WAV file that was grasped from the CD without loss, 44.1khz, which is the same as the CD indicator.
Finally, let me share the actual hearing difference between the two machines, due to everyone's likes and cognition is different, the following are some of my personal feelings to share, do not like to spray, if there are different opinions, welcome to civilized discussion in the comment area. Thank you all for your support.
First of all, the CD disc played by the Philips CD player, I personally think that the overall sound field is relatively open, the high and low three frequencies are more balanced, the intermediate frequency is not particularly prominent, the vocals are warm, sweet, and charming.
Next is the same song played with the computer, I think the biggest feature of 1541 is the vocals, the characteristics of the decoder playback are indeed so, with the CD than the vocals are more prominent, the medium frequency expression is very strong, the same sweet, the vocals are thick, there is a strong sense of encirclement, the sense of the scene, this decoder uses just the ordinary 1541A chip, and if you have the opportunity to find the real 1541A single crown chip, the sound should be better.
In fact, in terms of actual hearing, the difference between the two is not large, the advantage of the 1541 decoder is in the human voice, and the CD machine is more comprehensive and balanced. Which kind of machine sound do you prefer, please discuss the message in the comment area.
