One of my favorite albums, sound great!
I've tried newer chips, delta sigma even, Cirrus Logic and AKM ect', but prefer what I have.
I used to rip my CDs to my PC and feed a Cirrus Logic DAC from there, later it with Cinemag output transformers, I ended up going back to a CD60 which I modded, then now a dedicated transport based around the Philips CDM4/19 and the 1540D DAC.
Each to their own, we all like different things, there are many ways to approach this hobby.

If I print three zero's after the 1 on a 1 Euro note does that mean it's worth a thousand times more?If I print a crown on it, this chip is superior to those without a crown, etc.
And which chip may this be? Not that I find anything strange that highly processed and compressed pop sounds terrible.I'm not a fan of non-oversampling. If you want to know why, listen to Peter Gabriel's CD 'So', the track 'Sledgehammer'. The first ~8 seconds are unbearable for me with such a chip. So rough, so harsh.
Decent file playback is certainly possible but both difficult and expensive. A good old optical transport is often a better choice.
Since I've owned that particular CD for I don't know how long and a NOS DAC, I listened to the first 8 seconds (actually, the intro lasts almost double that) on both it and OS DACs. I cannot tell the difference.I'm not a fan of non-oversampling. If you want to know why, listen to Peter Gabriel's CD 'So', the track 'Sledgehammer'. The first ~8 seconds are unbearable for me with such a chip. So rough, so harsh. I understand it got other advantages but I have to say I have never heard a DAC in a CD player that tops any modern soundcard with 24bit, even surprisingly cheap ones. See, I don't want to star a war here but the prices of a TDA1541A now exceed easily high res sound cards and other DACs, which doesn't seem to be reasonable in any way. Please excuse my ignorance but why not just rip the CD and play it with a modern DAC?
My DAC is a Metrum Octave, what is your's?
I don't have that problem since I use my PC with a 24/192 sound card and even my USB 10 bucks sound card doesn't have any issue with that track but the CD player my father has, does. It has the TDA1540, it's one of the early Technics CD players, don't know the model.
I'm referring to the good old16 bit 44.1 kHz CD as a source on a NOS DAC.
AFAIK the TDA1540's 14 bit architecture is the reason why OS was invented in the first place, so that's probably not a NOS DAC in a commercial application.

Bonjour
je vais surement faire de la peine à certains mais
aucune puce r1 s1 ou s2 originale ne peut venir de taiwan!!!!!!
le réglage fait par les horlogers suisses Rolex dans les usines Philips a permis le réglage de cette puce
la couronne est le logo rolex
donc tda1541 pas de A
uniquement chez Philips hollande pas de logo Philips marquage
tda1541A r1 supérieur à tda1541A mais réglage pour obtenir s1 ou s2 tolérance impossible
???
s1 ou s2 toujours avec logo philips
mais jamais fabriqué à Taiwan
cette usurpation existe depuis longtemps maintenant
donc désolé si vous avez une puce fabriquée à Taiwan il
s'agit d'un original de base!!😛leurer:

There's many ways to skin a cat, perhaps a not too well implemented NOS Dac ?I'm not a fan of non-oversampling. If you want to know why, listen to Peter Gabriel's CD 'So', the track 'Sledgehammer'. The first ~8 seconds are unbearable for me with such a chip. So rough, so harsh. I understand it got other advantages but I have to say I have never heard a DAC in a CD player that tops any modern soundcard with 24bit, even surprisingly cheap ones.

Pop CD recordings are generally poorly done perhaps the NOS Dac is letting all that rubbish through.
Peter Gabriels "So" was praised for the recording and mastering and "Sledgehammer" was for a long time the track with the highest dynamic of a analog recording (AAD).
You probably have had issue with the dac itself then. I hear no issues whatsoever on the track. Played on three NOS dacs (pcm63, ad1865x2).
My experience is that every chip sounds a little different and the clock and all other mods together make it better than any hi-res bs of today. With no mods it's nothing really special. The most distinctive difference is what you do with the analog stage in my opinion. Old ceramic philips NE5532 opamps or tubes make a huge difference. PSU also makes big diff.
Greetings to all of you and enjoy the hobby. 🙂

I used to think like you too Sl1 but when you put enough effort onto the Tda itself the rewards plus gd analog stage
is beyond reproach

A priori il y'a des S2 de Taiwann....
The game is to make sound a Taiwann that is more precise : boldier, to make it sound better than an European made. It asks experiments.
Hi there,
it is not necessary to re-discover America, just reed the official documentation -

"s1 ou s2 toujours avec logo philips
mais jamais fabriqué à Taiwan"
"s1 or s2 always with philips logo
but never made in Taiwan"
I don't think that is true, my Marantz CD7 had taiwan chips, and two S2 chips I bought from a trusted seller here a decade ago also were from Taiwan.
Here is a picture of a CD7 from the web. People can check other pictures for themselves and read reviews where this is also stated.
Do you realise that the "R1" chip is the lowest quality, lower than a standard A?

There are three stages of production, Resposible center is Quality Control
Diffusion, Assembly and Responsible Centre
In your case RSH means
Diffusion: R
Sunnyvale, California
Assembly: S
Kaohsiung Taiwan
Responsible Center : H
Philips Semiconductors, Nijmegen, The Netherlands
So the chips are traveling a lot
Cheers

Don't laugh, but in 2025 it is very feasible they discover the best sounding TDA1541A were made in fact in America, lol !


For I, the european S1 & Taiwann 98 are two very different sandwiches of a same baguette, I love them both, but in my setup and the most style music I listen to, the T. has an edge, when suited with the good parts around. The S1 in I2S mode has an edgeVS the Sim mode. But I was said at the end when your pcb layout and shematic is good enough, attenuation of the front end, isolation where it counts, slew rate limiter, good I/V, symetric active FDEM pin16/17... then it is almost impossible to hear a chip difference.

Very organic natural sound. You either like it or don't.
My daily DAC uses a pair of TDA1540D chips, the original 14 bit DACs from Philips, in non over sampling. I added a i2s/hdmi board as the transport has that output, sounds better, more open and detailed.

Looks good and clean🙂
I have to take time to extract the TDA1540 of a moded Marantz CD player I have and I moded for an easy fire & forget little box to playback cd in a room ! But I like it so much I have pain to do it as an easy to live second system (you know, sometimes you just don't want to use the smartphone or the laptop but put a cd disc, then push the Play button, like the nowadays teens do with vynils because they don't know)
For sure it deserves like you did to work on a pcb and to have good care of the front end and the i/V stage. Maybe I will make mine...
There was a sympathetic pcb, which at last was made good at Alibaba to have a front end cpld based for the to chips. Basicly between the TDA1540s and the USB to I2S board (Amanero, Wave I/O, etc) : It looks like the one you have, probably same origin ? 🙂
What is your discrete I/V 3D stage please ?
