[Bernhard]

Hi.

due to my growing collection of 1541 and plan to try S2 if still available, I sell silvercrown on ebay.

And I guess I will have to sell 3 to get 1.

Guys were selling S1 for $50. I don't think S2 from Elib will be more than $70.

Guys,
stupid request: do u mind briefing me on WTBD is with TDA 1541s?

Fashion, I suspect...

What does WTBD mean ?

 

[Peter Daniel]

I think he meant What The Big Deal, (if I know him well enough)

PS: If you asked WTBD with TDA1543, I would tell you. I didn't try TDA1541 enough yet.

Is S2 worth the money ?

I would like to hear opinions from people who have spent the big $$$ on the double crown from elib.

 

[Bernhard]

If you asked WTBD with TDA1543, I would tell you.

IMHO parallel chips can be dangerous.
After measuring all my 1541 in non os mode today, I also tried another 2 in parallel and one channel completely ( all harmonics ) improved while the other one got worse , also completely.

This is like gambling in Las Vegas.

 

[Peter Daniel]

I don't like parallel chips.

And most people who tried S2 from Elib, where selling their S1's.

To me, S2 sounds much better than either regular version or S1.

IMHO parallel chips can be dangerous.

At last you see it ! It is also difficult enough to design a good DAC layout with only one chip.

S2 really is worth the money.Very smooth highs and big difference compared with S1. Much bigger difference as between S1 and normal A version.

I wonder how they will behave on your analyzer ....

About the S2...

Jean Paul, you told that the S2 were produced later (97 I think), but did also other chips be produced (S1, regular, R1) at the same time, or did philips manage to produce 100% S2 chips? (or 3rd solution, they destroyed all those that didn't qualify as S2)

 

[jean-paul]

I don't know that but I have never seen either normal A, A/S1 or A/R1 with 1997 datestamps ( Bernhards S1 are stamped 1996, first time I see such recent S1 as well ). I learnt that S2 were specially produced in Taiwan for Marantz CD 7. I was told that production quality was very high so the theory that most were qualified as S2 may hold. Earlier S2 were certainly not made in Taiwan ( BTW they were awfully expensive at that time too ).

Mostly speculation really as all this is from audio-magazines and hearsay, I've not seen this info written in official Philips documentation. S2 seems a bit obscure in that aspect. Fact is that they do sound the best and that Zanden bought the last batches of them. I don't know how they measure, I've only recently tried one of the S2 I bought. The S2 Elib offers are genuine, I don't trust the large amount of "real" S1 offered on the web.

Marantz CD-7

Re: Marantz CD-7

Peter, do you have a bigger pic ?

 

[Peter Daniel]

Of course I do

 

[Peter Daniel]

Heres the input logic. It looks like I2S signal is divided into R and L data (from the digital filter) and two TDA1541 chips are used in balanced mode, one per channel.

 

[Peter Daniel]

Here's the left channel

 

[Peter Daniel]

And here's the right channel
